Community Voice & Feedback
It literally won’t work just say your region doesn’t allow Line
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.
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.

There’s no option to disable many annoying features. The chat history search often fails to find existing messages or returns incomplete results.
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.
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
sucks to know that I can’t log in to my account because my phone broke
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
I wish they add LINE PAY in the US. I’ve been using this app nearly 15+ years and I moved to the US thinking I try to buy something on LINE but it’s doesn’t have US payment like PayPal and I wish they add that
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.
I can’t log in line acc again . When i log into it it show me “vitrification is temporarily blocked “
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.
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.

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.
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.
