Will a droid razrrm SIM card work for an iPhone 4S?

I have a droid razrrm with a Verizon SIM card, but I want I activated friends old iPhone 4S, will it work if I put the droid sim into the iPhone?

Well, no. The reason I say this is because the iPhone 4S is still a 3G enabled phone with ZERO global capability (in Verizon's network anyways). And because it's a 3G phone, it lacks the SIM card functionality that other iPhones in the equivalent GSM networks have. You're out of luck if you wanted to use the iPhone 4S with your SIM card. Hope this helped.

NOTE: You can still use the iPhone so long as the ESN is clean and if the phone can be wiped, but you need to contact Verizon in order to get the stuff through.

Likely not. Verizon is a CDMA carrier which does not use SIM cards. That SIM is likely for data use only, not like other SIMs on GSM carriers which is used for that as well as phone/text. Also it depends on which carrier the 4s is set for.
