Hi,i think the phone's ROM should be flashed entirely in order to restore your phone back in a perfect working condition,however,this involves the use of a particular software which costs up to $40 and requires adequate skill and techniques.

Thanks and take care

    how can i do this? most people think it could be a hypersim card prob. i dont really know what it could be. sometimes when i switch it off, i see signal bars, but it dont last. what would i need to get?

    you can try to use another sim card with the phone,if the problem persists it means the problem is from the phone and needs to be flashed,but if the problem disappears it means the problem is from the sim card,however,your phone can be flashed only by a qualified phone technician

    do u mean another tmobile sim? and can u describe how a phone is flashed? and if all else fails, do u recommend any 1 or place i can send the cell 2 to do the necessary requirements? this is something i dont know about, only wat ive seen on youtube videos. but all they show is how 2 cut a sim 2 fit in with a hypersim. and i doubt a tmobile store would know about a japanese cell. but im willing 2 do watever to make this cell hav signal.

    Hi,i think you should try another sim from t-mobile as well,however,you can make a quick search on the phone technicians in your locality to find the closest one in your area to help you solve your problem.

    Thanks and take care

    I think you should try to use another sim either from t-mobile or any other network just to know if the problem is from the sim or the phone itself,you can make a quick search on the list of phone technicians in your area,to help you solve your problem.

    Good luck!!!!!!!!

Okay i have tmobile service but i broke my phone and my mom bought me a tracfone to put my sim card in, but it says sim lock code. So i guess my question is that is there anyway i can use my tmobile sim...


Well like most carries I believe tracfone will not let you use a tmobile sim card because the phone is locked to tracfone only. Typically you could unlock your phone to use with any service provider that uses sim cards. However I do not have the process instructions for your particular phone model.

You can purchase unlocked phones on, ebay etc. If you are satisfied with your tmobile service perhaps you could always get a tmobile phone.

Post back if you have any further questions. Thank you for choosing Fixya.

Contact your network service provider and request the subsidy unlock code or purchase the subsidy unlock code from a third-party. I have posted a link below to an online service that supplies Motorola Subsidy Codes for £7.00.

Please Help me to unlock in Globe sim card , Philippines

Call your cell phone carriers customer service and they may email you the unlock code and instruction for free within 24-48 hours. Tmobile did this for me several times on different phones. Alot of cell phone stores and kiosks will also unlock any cell phone for you for about $30.00. You may have to leave the phone with them and pick it up later like an hour or two later if they are busy.

Softbank 911T

Even if the phone is unlocked it might not work on the Philippines network. The Japanese Softbank 911T is manufactured by Toshiba and uses 3G WCDMA 2100MHz. China uses 3G TD-SCDMA. China Unicom is going WCDMA as well soon. Enquire at your service provider, if it can be made to work, they will do it. I don't really know about the Philippines. Great phone though.
