No longer can transfer in US
Got a new iphone in US and now they won’t let you transfer unless you have line open on your own phone to scan QR code. no more signing up with US phone number’s. Can make a new account either, so that’s it no more Line
Completely locked out
Just terrible
cant transfer from my "main" account because phone is too old
i dont understand why this company cant get its act together with account transfers. always the most convoluted process when i have to do it. got a new phone but i cant log in because my old phone is on the ancient version 13.1 and cant receive verification requests plus the app blocks me out of interacting with it to generate a qr code. why cant i generate a qr code or link my account to my apple id from my ipad or on pc? why can i only do this on my "main" device?
Terrible customer service
I randomly got kicked out of my new LINE account and was barred from logging in again with “verification temporarily blocked” messages. I attempted to contact someone to help me recover my account, got the runaround with their inquiry forms, and still haven’t been able to speak with someone through a phone call or email correspondence. I can’t make a new account either because it only gives me the option to make the account with my Apple ID, and mine is already tied to the blocked account. Terrible experience, 10/10 would not recommend.
WARNING to everyone living abroad (especially with only ONE phone)!
LINE’s account recovery system is an absolute joke and a total nightmare. If you only have one device and happen to delete the app or get logged out, you are completely screwed. The system gets stuck in a stupid, endless loop forcing you to scan a QR code from your "old device" which obviously doesn't exist if you only have one phone!
To make matters worse, if you are in the US, it won't even let you verify via phone number easily. I just lost access to my account, which has incredibly important work data inside, all because of this flawed, outdated system.
DO NOT delete your app, DO NOT log out, and make sure you link your email/Apple ID right now before it’s too late. Don't learn it the hard way like I did. LINE support is useless

Garbage app
Requires old broken phone to transfer to a new one. Waste.

Очень плохо что приложение не работает в России👎🏻
Poor Design & Lack of Support
They can randomly suspend you and will give you no information regarding why. It is practically unusable, avoid if you have any other method of contacting people. Have had nothing but problems
Unable to log in
I have only had this app for 1 week and I started having issues with all of the features in the app. I am unable to click on anything in the app other than chats. I wasn't able to use sticker shop etc. I deleted the app and reinstalled hoping that would fix the problem. However, after I reinstalled the and tried to log in, it kept saying ''verification is temporarily blocked'' and when I reached out to LINE support, they said it was due to me violating their terms of use e.g. abusive language, obscene content, obscene expressions. Mind you, I have only had this app for one week, and added only 1 friend and I am in 1 group chat with parents from a children's karate class. I have not sent ANY messages yet. LINE support is absolutely no help. This entire situation is ridiculous
Verification blocked?
I deleted line and redownloaded it in the same 5 minutes, I try to log in with Apple and it says verification blocked, I need to log in but this error keeps showing up, even after waiting 24 hours.
Line doesn’t work for US
It literally won’t work just say your region doesn’t allow Line
The worst app the ratings don't lie
Please don't get it - if you lose your phone you could potentially lose ALL your contacts FOREVER AND THEY DO NOT HELP YOU GET IT BACK.
Unacceptable Account Recovery Experience
LINE’s account transfer system is absolutely terrible. I changed devices and it would not let me transfer my account with my own phone number. This is absurd. A messaging app should not make users risk losing their account just because they got a new phone.
The process is confusing, restrictive, and poorly explained. This is one of the worst account recovery experiences I have ever had.

Too Much Bloat
There’s no option to disable many annoying features. The chat history search often fails to find existing messages or returns incomplete results.
Good Luck
I got a new phone and I’ve completely lost access to my account. I was logged out on my ipad at the time and couldn’t recover it that way either. There goes over 14 years of chats.
Ugh
Why is it that it’s telling me to sign in, which I’m doing and it keep on telling me to go into my account. If I can’t sign into my account how is it that I’m gonna get whatever code is send into my account. I’ve used my Apple account and I’ve also used my google account and it’s still telling me the same thing, and it’s telling me I can’t use my phone number cause it’s not allowed in my region anymore. How can I delete it and start over again. For the love of god
can’t log in - new phone
sucks to know that I can’t log in to my account because my phone broke
Awful if you get a new phone
Just as the many reviews mentioned, I have tried logging in with my phone number, Apple ID and Google and was unsuccessful. I even tried to create a new account and still couldn’t get it. Just forget this App and find another one through the APP Store
Worst app ever
This app is the worst app I have ever used. My phone broke and I got locked out of my line account. I provided my phone number AND password but unless I could access my BROKEN PHONE I couldn’t get back into LINE. If you read their flow chart of FAQs it says “if you can’t access your old device, login with your phone number.” Then when I do that it says “access your old device.” How does that make any sense?? Surely if I could summon my broken phone to work again I wouldn’t need to re-login, right? Now I lost all my contacts despite being able to provide all my login credentials. Even when I was able to use this app I randomly wouldn’t receive notifications, messages would appear on lock screen and not in the messages (no, it’s not my phone’s fault-this only happens on LINE). Seriously, do not use this app. Use WhatsApp, Facebook messenger, or even good old fashioned letter writing would be easier than using this app.
Worst app ever
This is the worst app to every exist. Customer support is so terrible and does nothing. I couldn’t log into the app. Nothing works.
Account Transfer Code
I recently went into Apple for a battery replacement but Apple broke my phone during the repair and gave me a brand new unit. I now need to setup my new phone and as I was trying to login to line, it requires a Transfer Code from a device that’s “already” logged in which makes no sense since the phone that was “logged in” is now broken and is not in my possession.
when I try to create a new account it says your Apple ID is already being used! So stupid I can’t even log back into my account without another device already being logged in. no way to bypass this either so now I cannot even use line anymore.

Suspended my account for no reason
I am going to Japan for a cultural exchange trip and it was recommended I download line. I set up my account about a week before my trip and didn’t touch it. I tried to add some friends on the app and it was giving be error codes. It started showing me a message that said my account had temporarily been suspended which is weird because I literally had not touched the app. It does not specify why I was suspended or how long it will be. I just don’t understand what I could have done that was against lines terms or service considering all I did was set up an account.
No way to recover your account if you lose access to your old phone
Could any of the LINE software engineers please fix this bug? A lot of users are complaining about it.
I lost my old phone and am trying to log in on a new device using the same phone number, but there is no option to log in with a phone number in the US. There is also no email login option on mobile devices. Instead, the app forces users to sign in with Apple ID or Google ID, and the same email address doesn’t work through those SSO paths.
This creates a situation where users can be completely locked out of their accounts after losing or replacing a phone.

No video chat pip
No video chat pip still. It’s already 2026
Log in issues
How do I verify my line account if was logged into only one device?
lol
lol
Lost my account due to ban US number
They no longer US number login, we lost our digital property
Impossible to work with
My parents set on a parental control app which includes a VPN I can’t take off. This app won’t let me do ANYTHING with this vpn on. I confirmed it was the vpn by taking it off and before it automatically reconnected (a few secs) I sent a message to someone. It sent. Then when the vpn reconnected nothing sent or worked. I couldn’t set an ID, a status, add anyone, and I couldn’t do anything. It’s annoying, really.
Log in issues
Would not even go a 1 star at this point unfortunately. Used to be able to log in by phone number now it’s not an option in the USA, even though the servicer by text messages and phone calls through verification are through USA and other countries. My email has been verified through Apple and is saying it is not. So another option is through a QR code which I do not have or set up another line app. I had to reinstall the app because I was not getting notifications when I reinstalled I haven’t been able to log back in since. App completely sucks wouldn’t recommend to anyone unless of course it changes back to being able to log back in by using phone number through USA again.
USA - Can’t access my account anymore
Got a new phone, didn’t know I needed my old phone to transfer - huge mistake apparently. Cannot use phone number to login. No option on the app to use email and password (which I have) - only Apple ID or Google. Even though both are associated with my email, LINE says they can’t identify any existing account - even though when I use google, the google app screen says “I’m signing back in” to LINE. Still can’t get in. Tried creating a new account but if I try to add my email it says it will unlink from my old account (acknowledging it exists in the first place) and only be used with my new account. So basically LINE knows my account is there and none of its login methods is smart enough or working to link the 2 accounts together. The “inquiry” form is terrible and doesn’t allow free typing so you have to choose the right prompts and attach screenshots and just hope you did it right. Currently waiting for a reply from support.
Losing my 10+ yrs account
Didn’t know you cannot login with your phone number in the US now. Recently got a new phone and couldn’t verify my account through my number and Apple ID, and the inquiry form page is pretty much 100% useless. Now it looks like I’m about to lose my account that I’ve created almost 15 years ago. This company is absolutely ridiculous and makes me nauseous just thinking about how much money and time I’ve wasted on this app.
Not ideal for iPhone
I’m having same problem everyone that gets new iPhone if you didn’t transfer your account you can’t log back in or make new account
Couldn’t log in like before
Usually I log in by username and password or phone number but now I can’t so sad with that. It shows just scan QR code from another device. I have iPad it didn’t show easy transfer device that they show how to do it for me at all. I had use phone number to login before too but now can’t too it shows I can’t use in my country (USA) it made me very disappointed. I have a lot of friend and family in there. I couldn't use this application anymore.
No support help whatsoever
The login process is messed up. If you ever forget your password, its sadly a goodbye to your account as you can’t chat with anyone to recover it, to reset your password you need to login with your password (makes no sense). Even if you do know your email or apple account, you won’t be able to log in as Line conveniently “forgets” you have an account tied to that email. Horrible and not user-friendly.
Won’t even let me log in
I’ve been locked out of my account for a while and I can’t recover it. Support/ help pages that can be accessed without having to log in are unhelpful. No longer have contact with my host family and friends I made in Japan! Spent a lot of money on themes and games too.
U.S. phone numbers are not supported.

This App sucks if you have an Issue
Why is there no one you can contact if you have an issue? The app just has a list of issues you can submit - but if you try to contact anyone there is t anything you can do. Screw this app.
Definitely not recommended
I am very disappointed with my experience using LINE. I lost access to my account, which is essential for my work communication, and the recovery process has been extremely difficult and confusing. Even though I have access to the email associated with my account, I have not been able to recover it successfully.
The account recovery options are limited, and the instructions provided are not clear enough for users outside the supported regions. This has caused significant inconvenience and affected my ability to communicate with my company.
I hope LINE improves its account recovery process and provides better support for users who rely on the app for professional communication.

Annoying not available in your country error
It keeps popping up “the service isn’t available in your country/region” when I was visiting Taiwan. I tried several ways but still failed to get around it. Very disappointed by their region control.
US users can only create an account using apple
Traded in my old device containing Line for a new device and forgot to switch the account transfer settings on, tried logging on but failed since I no longer had my old device or a transfer QR. One star since there’s no option to create a new account using Google or a Phone Number, they should add that option instead of limiting it to an Apple Account.
Can’t log in after phone was stolen
This app is the worst. They won’t allow you to login to a new device if you no longer have that device. And you can’t create a new account if it’s the same phone number.
Questionable Suspension
I was in Taiwan when I downloaded line as that is the primary form of communication. I was in a single group chat with family members when suddenly I could no longer send messages. When inquiring about why my account was suspended, line said that they could not provide any information regarding the reason for or duration of suspension, which makes it impossible to recover my account. It has been over a year now since my account has been suspended. It is neither logical nor conductive to user experience to provide no reasoning behind the suspension. Furthermore, it is nearly impossible to get in contact with support staff to resolve this issue. I do not understand why anyone would use this app as their primary source of communication. There are several better structured, more secure, and streamlined apps that could otherwise be used. This has been an exceptionally frustrating experience.
Transfer account between iphones not possible
Poorly made app. Line on my old iphone says "have the new iphone scan the QR code to transfer the account to the new iphone" but LINE (updated version, if course) on my new iphone shows only two ways to transfer: one is to use a phone number (which is not available in US according to the app's own help for transfer-- ridiculous), two is to use an Apple account (which I do not want to, and based on the review here, it will cause the problem for the future transfer). Why do you make the transfer between iphones nearly impossible? I understand why more people are shifting to whatsapp as it causes less hassle and does the same job basically. Do better.
Get WhatsApp instead
Plan on never losing your phone if you get this app. You’ll never be able to log in again.
I’ve been stuck in the transfer verification loop and there is no way out. Getting a new phone has bricked this application. Especially frustrating since I have lost chats and photos with my friends in Japan. As well as the sticker packs I paid money for.
You cannot verify with phone number in the US. You cannot log in using Apple ID without the previous device. You can’t create a new account because your Apple ID is already in use.
Absolutely ridiculous.
There is no support to reach out to either.

Login
Logging in using your phone number in the US has now become non existent. Help desk is of no help with recovering or allowing accounts to be merged with verification. I really use to like this app but is absolutely useless since I can’t recover my account after resetting my phone.
Poor customer service
Can’t log in or create a new account. Responses don’t help.
Fix recovery options for account in the US
Absolutely worthless app. I have been trying to recover my account for days now because my phone was lost and I don’t have access to my old phone obviously so I can’t transfer my LINE to my new phone because I don’t have access to my old phone which I guess I need in order to manually transfer it to new phone in the United States.
Trash

Terrible Login
Can’t login because USA won’t allow phone numbers anymore. Can’t access with my email either. Not happy. Next.
Cannot add people
Cannot add people from their number or ID. Before was super easy, but now need to see what version they have and when was made it. Really annoying. Fix it
