Piranha Mobile Sim Card

I do not see why not, since you said it's unlocked. Mine works in my unlocked AT&T Iphone 4.

The SIM works perfectly in my Moto G.

It appears that it has to do with the default crippled mode of AT&T phones. When I insert my T-Mobile PAYG SIM, after a few minutes it updates the settings and give me the manual carrier selection menu and T-Mobile STK. With the Piranha SIM it does not do this. The phone has iOS 6.1.6, which is up-to-date for this phone. I'm also getting advice from Piranha Mobile but so far, no joy.

I wanted to use the old iPhone 3G because it has all the needed bands and is expendable.
