Once we are talking about unlocking, you may think about software tweaking which basically hurt the whole warranty of your device. For those who has Dell Streak 7 on T-Mobile network and want to enjoy the fast speed from AT&T 3G and HSPA+ network. Well unlocking T-Mobile Dell Streak 7 doesn’t require to break through any of your device’s root but a code and AT&T sim.
Do you want to enjoy the HSPA+? Actually Dell Streak 7 supports both 1700 – 2100 MHz and 850-1900 MHZ bands but some actions are required. Just as what I told you, there is nothing to do with your device root but the processes are not free.
The unlock is offered by unlockstreak and you have to spend $49. By sending them this payment and IMEI number of your Dell Streak 7, you will receive an unlock code. You now can insert another carrier sim and you have to insert the unlock code when it prompted.
If everything is done, you will notice your device now works with the new carrier. Of course new network is coming along too.
