The "Correct size sim" doesn't apply here. I also have a CSPIRE 4S you have to have a IMEI unlock code. The Sim Slot is hardware locked to CSPIRE and "their" international SIM that they Sell. I tried to get them to unlock mine and the promissed to look in to it and call back... Of course they never did. Services online claim to provide this service but i've yet to try one.
