New 6s not having LTE and showing 'No Service'

[deedeebear]

So yesterday I decided to part with my iPhone 6 Plus and get a iPhone 6s. Still getting used to having a smaller screen but anyway back to my main issue:

Ever since I got the phone I have not seen LTE and most of the time it either says No Service or 3G. On my 6 plus I would mostly be on LTE. I wonder what's going on if I have a dud or something. Just wanted your input before I go in and exchange.

Do you have LTE checked in Settings > Mobile Data > Voice & Data?

Need more details... but my first thought would be a SIM card issue, have you contacted your carrier?

Under Cellular I have LTE checked and now I just checked data under roaming. It was only checked for voice. Is that the category you're talking about?

Funny that you say that because I just got this message on my phone.

The roaming setting is only applicable when you are outside of your carrier coverage (in your case Sprint.) I would call or visit a Sprint Store and tell/show them what is going on. I know with Tmo I have to call them when I switch iPhones to activate the right SIM card with the right iPhone... it's not automatic the first time like I used to do with AT&T.

Also you might try resetting your network settings on the iPhone... go to settings/general/reset/reset network settings. Note, you will lose all your saved Wi-Fi networks when you do this...

Our data settings menu is a bit different over here, but it looks like you already have LTE checked which is what I was talking about. We don't have a voice option for roaming, only data, so I'm not sure what that does.

 

[deedeebear]

Yeah it's a bit different so I'll probably call Sprint about this. Here are my two screens under cellular.

One other quick thought -- is the iOS up to date with 9.1? If not get on Wi-Fi and update. Your Cellular menu looks different than mine too... but it might be carrier specific (I'm on Tmo...)

I've had that problem before. It was my SIM card. Contact your carrier to get a new one.

Exactly what I was gonna say. I'm with Fido and had this problem on my last 2 phones so I recognized the problem. Just contact your carrier and say your plan was not activated from their end. They'll reset the plan on your carrier and you're good to go

It was my SIM card! So annoying. I mean it wasn't even attached to my account. The rep who was helping me activate my phone did not attach the SIM. Now I have LTE!

Could this also be the reason why I'm not seeing band 12 on my 6S Plus with T-Mobile? I popped my sim from the 6 Plus I was using to my 6S Plus and we're supposed to have band 12 where I live.

To be honest I'm not very familiar with SIM cards since I've been with Sprint ever since 2004 and I didn't even know CDMA phones required them. I guess with the iPhone 6s they do since they gave me a universal 6s and said they would just give me a SIM and it would work on Sprint.

All I know is that my LTE would not function without the SIM being attached to my account.

How do you know that you are not "seeing" Tmo band 12? To my knowledge there is no way to tell on an iPhone like you can with Android... unless you are interpolating signal strength and coverage and making assumptions...?

Ah... forgot about the hidden field test mode in iOS...

It's not really hidden. Anyone with an iPhone can use it.

CDMA 2000 networks in North America don't require them, but LTE does.

Oh I see. I understand now. Thank you!
