I want to use RSIM to unlock my iPhone (AT&T) and use it on Aio. Does anybody have experience with the RSIM?
You don't need it, AIO works on any ATT locked phone including iPhones.
I'd just get an AT&T Compatible Straight Talk SIM from Walmart.
Then cut it to micro/nano...
Then port your number into Straight Talk.
Enjoy Unlimited calling, and text... with 2.5 GB data...
on AT&T's LTE network!
For only $41/mo (with no tax!) by purchasing Straight Talk airtime pins from CrazyGameTime.com!
I'm on straight talk. I NEED out of them. They throttle cone to 0.00 Mbps, which is not usable. Plus, aio has 7 GB for $70
If you use Straight Talk isn't your phone already unlocked? As to your original question, I haven't used RSIM, but it looks good.
