The original Turbo SIM answered a single boot query claiming that it was an AT&T SIM; all subsequent questions passed through to the real SIM, and so the baseband was able to talk to the local GSM network without problems.
Apple modified the baseband firmware to the use of the Turbo SIM by performing two queries. These would not match, and the SIM rejected as invalid. The fix for Apple’s fix was to answer the first two questions with the AT&T SIM ID, and subsequent requests with the actual SIM ID.
Turbo Sim Will Work Forever? – NO
Apple further modified the baseband firmware to the use of the Turbo SIM by performing a query on tower hand-off. Tellingly, when your iPhone was handed off from one cell tower to another, it would re-query the SIM, and the Turbo SIM would not answer, and so it would not be an AT&T SIM ID, and the cell would lock up. But as long as you did not move between cell towers (i.e., you were not relatively stationary in a coverage overlap zone, and you were not running between zones, e.g., traveling by car, train, etc.), it was functional.
Here where things in the arms race currently stand. Buy an Unlocked iPhone instead of using Turbo SIM.
Should this escalate further, the obvious answer for Apple is also to modify the baseband firmware and have it do the initial query, and cache the result? If it were to do so, a Turbo SIM claiming to be an AT&T SIM to the iPhone would have that SIM ID contended to the cellular network. And the iPhone would just not work at all, whatsoever.
It May done in an iOS update.
So your best bet would be just to buy an unlocked iPhone, rather than purchasing a locked iPhone and trying to spoof the carrier.
