Thread: Can't Change SMSC Address w/ Gevey Ultra S

  1. #1
    Default Can't Change SMSC Address w/ Gevey Ultra S
    Hi. I finally got my iPhone 4S connected with the Gevey Ultra S through T-Mobile, but I get 'Message Send Failed' every time, when sending both SMS and MMS. My iPhone is 5.1, with baseband 2.0.10.

    I think I've narrowed it down to the SMSC number. When typing in '*#5005*7672#', it tells me the current SMSC number is '+7'. When I try to change it to the T-Mobile SMSC number by using '**5005*7672*+12063130004#', I get the following message:

    Setting Succeeded
    Service Center Address
    No Address

    Does anyone know why it won't change? I've done everything I can think of, and went all across the web looking for a solution, but nothing. Everything else works fine, (EDGE Data, Voice, Incoming SMS) with the exception of MMS, which I could really care less about right now. Does anyone know how to solve this?

    1. reset network settings
    2. pop sim out, power down, power up, when "no sim" is prompted, push sim in
    3. sync with itunes
    4. open ibackupbot and edit "Library/Preferences/com.apple.mms_override.plist" and "SystemConfigure/preferences.plist" just as Westc0ast listed(fix mms error t-mobile unlocked NOT jailbroken)
    5. Save them, then mark both of these boxes with checkmarks and restore via ibackupbot
    6. Once ibackupbot says restore has been successful, remove sim and let iphone power down automatically, then power up again
    7. when "no sim" is prompted, push sim in. When Gevey software unlocks iphone and tmobile appears, you are good to go!

    thank you for your help and i hope this helps others who have a white iphone 4s running ios 5.1, firmware 2.0.10 with a gevey ultra s
    hope this helps.
