    Hey guys, got a question. I was playing around with my old iPhone4 and restoring a back up to it, when it suddenly needed a SIM card to reactivate. So, I borrowed the SIM from my Nokia 920 to get this done, but when I put it back in my 920, a message popped up that read: "Phone change GSM mode" (something like that)

    Anything I need to be concerned with here? I checked Access Point and my LTE1 & LTE2 are still there and I'm still getting LTE speeds with about 4 bars of LTE in the status bar.

    After another reboot, the message didn't come back.

    Generally speaking, I don't pop SIM cards in and out while the phone is on for that reason. I always shut down, remove/reinsert SIM, power back on.

    Oh that's how I did it. Both were off when I removed and inserted the SIM. It was when I powered the 920 back up, that it initially gave me the GSM message.

    You're fine, when I change SIMs on my 928 it goes into either "LTE and CDMA" mode, "Global Mode" and "LTE, GSM and UMTS" mode.
