When T-mobile bans your Sony Xperia Z1S LG G Flexsmart-phone for outstanding balance (and believe me they do ban it). Here is what you can do.
- You can pay off the balance.
- You can use some online services that offer IMEI ban unlocking so you can use your phone again. These online services often person the IMEI unblock same day online and you don’t have to send in your phone. Unlock Pros is a good example of one that does this. These online websites specialize in bad IMEI repair. I don’t know how they do it legally.
- If it’s a stolen phone that has been IMEI blocked, it is a good idea to return it to a T-Mobile store so original owner can have it back.
AT&T, Verizon and Sprint also does banning of IMEI’s and EIN numbers.
