I am in the last month of my service w/Cingular and decided to, just for grins, pop my wife's TMO sim card into my phone 7290. I was able to make a call and had very strong service here at the house (something I do not get with Cing).
Could my phone be unlocked?
Phone also said "data service not available" I assume it was not reading data from TMO.
Does TMO support the 7290?
can I sign up with them in another month and go with their service?
When I first got my phone I tried the same thing with the TMO SIM card and it did not work. The only thing I have done lately was contact a guy at GSMPHONESOURCE http://www.gsmphonesource.com/
I paid him $45 to unlock, but he ended up refunding my money because he could not find the unlock code for my IMEI...now my phone may be unlocked!
