upgraded from iPhone SE to iPhone 7 - no service?

[gbaker]

I updated my iPhone from SE to 7, and figured all i had to do was swap out the sim card.  No matter what I try it just keeps saying 'no service'.
I've tried rebooting; taking it out and back in again... etc etc.... nothing!

@gbaker try updating your carrier app

 tap Settings > General > About and tap on carrier

Hi @gbaker  - This is a tricky one.

"A glitch in the wireless network roaming partner of your carrier can cause this when it gets you onboard their network per their agreement with your carrier. Such problems are common worldwide. Users report that turning the voice roaming setting off and on again often resolves a "no service" problem."

Maybe this is worth a shot:

Turning on voice roaming may incur roaming charges.

1. From the Home screen, navigate: Settings  > Cellular > Cellular Data Options.  If unavailable, swipe left to access the App Library.
2. Tap Roaming.
3. Tap the Voice Roaming switch to turn on  or off  Voice Roaming must be on for the Data Roaming and International CDMA options to be available.
4. Tap the International CDMA switch to turn on or off.

Also you could try, lightly blow into the SIM slot (without the SIM in it).

I won't be able to do that, unfortunately as I don't have another iPhone / sim card

[gbaker]

it is possible.  I'll message them.  It was bought through a secondary retailer but on the BestBuy website.

HEllo @gbaker ,

Have you tried someone else's working SIM, preferably a Public Mobile customer, but if not an active one in the 7 phone?

[gbaker]

Still nothing!

And, also tried the airplane mode; reset of network etc. etc... nothing.

[gbaker]

trying now... it wasn't, no.  updating to iOS 14.1 now

@gbaker 

Is your ios up to date?

@gbaker 

If possible, maybe  try a different working SIM card in the iPhone 7. 

Since the PM SIM card works with your old iPhone, PM service end is fine. It is an issue with the iPhon 7.  Possibly defective?

[gbaker]

Tried that as well!  All things the 'bot' asked me prior to coming to the chat.

@gbaker 

Is it possible that the iPhone 7 is locked to previous carrier?  

maybe try network reset of the iPhone 7

[gbaker]

got it from best buy (a retailer).  Unlocked.
Checked it for stolen etc. on the public website - all good.

[gbaker]

Thank you for replying. Yes, me SE worked fine - and still does. It's when I put the same SIM card into the 7 it says No Sim. Yes, my status is "ACTIVE". I did try the Airplane mode off / on but it didn't work. Hoping we can resolve this. Thanks.

Where did you get the i7...if you got it used, make sure it's not been reported as lost/stolen and blacklisted somewhere. Go to the top of this page and click Get Started, scroll down to the compatibly area and there's a lost / stolen tool in there.

Keep us posted how you make out.

Hello @gbaker , 

I assume everything worked in your SE phone?

What does is say for your status in your SELF SERVE account?

• Try going into airplane mode for a few minutes, then back to normal mode.
• Do you have the latest version on the 7 phone?
• You could try to reset your factory defaults
