Turbosim Stopped Working

[bhorvati]

Turbosim was working fine for over a month.

Now says invalid SIM.

I have a new 3G phone with T-mobile service. I purchased the 3G off ebay it was already unlocked.

I read that putting T-mobile sim back in an another phone and placing calls with it and then putting back in i-phone with Turbosim would work, but it didn't.

I have not tried to reset i-phone yet. Is this software or hardware issued?

Here are my settings (which were working just fine):

APN: wap.voicestream.com
3G: OFF
DataRoam: ON

It is a problem with your unlock sim card. It happens wit some unlock cards. Instead you could try the 3G simcard from Unlock iPhone 3G - Instant Unlock any iPhone
Good luck!

i have tried 4 different turbo sims. The smartphone sim unlock seems to be the best. i always advise buying 2, using one for a back up.
