Using a LTE sim in 4s
I don't know if this was addressed on here yet or not, so i apologize if it is, but here goes:
I have a VZW iphone 4s, and a Droid RAZR. I know the 4s has a sim card pre-installed for global use, but im wondering if there is any way to make it so the sim card from the droid can be used in the iphone so i could switch back and fourth from the 4s to the razr. Now i know my iphone is CDMA and that LTE is basically GSM but im wondering if i get it carrier unlocked the phone would recodnize the sim with my number and work? Probably a long shot but i figured this was the place to ask

I tried using my dad's Verizon iPad's SIM in my AT&T 4S (carrier unlocked) - I thought maybe it'd work since the 4S does have CDMA hardware. But it never picked up a signal

I realize this thread is about VZW...
I just thought I would mention that ATT's LTE sims will work perfectly fine in the 4S (personal experience), and presumably the 4, and even older iPhones with the appropriate size adapter.
I use iOS and Android daily and, more recently, Windows Phone 8. If what I say upsets you, it's probably because of your brand loyalty.

Just because the technology is based on GSM does not mean poping in a sim card will make it work. You need an LTE radio on Verizon's 4G Bands (700Mhz C-Block) in order for it to work. You can take a 4G sim and place it into another Verizon 4G product and it's all good and dandy, but the iPhone will not work. The CDMA work's because the activation of the phone is still the same. The CDMA is still Voice only and the 4G LTE network is only data. I can get into a whole thing about eHRPD and why a 4G sim in another 4G phone activates it but this is a general sharing of knowledge.
