iPhone 7 Plus No Service When Turn off LTE

[CHASESCOTT66]

Just switched over from T-Mobile on Saturday, but Apple traded my iPhone in on Friday for the "sim-free" version that would work with Verizon in advance of the switch. Anyways, when I disable LTE  or set it to Data Only under the Enable LTE menu, my phone goes to No Service. It doesn't seem my phone is connecting to the 3g network. I am worried because where I travel for work sometimes only has 3g service and I don't want to be without service in those spots.

Are you sure you got the right version? AT&T and T-Mobile do not have the CDMA radio. I would go back to Apple and confirm.

[CHASESCOTT66]

Yes, it's model A1661, as stated on the back of the device, the model that has the CDMA radios in it.

I traveled to an area where no LTE was present, but 3G was. My phone went to no service, while my friend's phone was connected to the Verizon 3G network.

I took my phone to Apple yesterday and they exchanged it due to "faulty equipment." The new phone worked yesterday when I would disable LTE, as it would connect to the 3G network. But now today it is doing the same exact thing. It will go to No Service when I disable LTE and also when I switch LTE to Data Only.

I am beginning to think the problem is on Verizon's side.

Try getting a new SIM at a Verizon corporate store.

Have been through 3 sims and 2 phones, still not answers......

CHASESCOTT66, we want to keep you connected where ever you travel. You mentioned that you received a warranty replacement phone. The sim card in your device is what keeps you connected to our network. Did the Apple Store location provide you with a new sim card, as well?

[CHASESCOTT66]

I went to Verizon and hey switched the SIM card in the store.
