I guess I'm OK on that because my phone is an unlocked, O2 Pearl using T-Mobile as a provider. Maybe that's why it seems (and is) OK. I've used a French SIM, T-Mobile "to-go" SIM and now T-Mobile flex-pay account SIM in this thing and they've all worked great. I've saved the instructions in case I need them later.

Thanks again for everything. See you in the stacks.
