Hey Stupidapplee,


It sounds like you have already performed most of the steps in If you see No Service, Searching, or SOS on your iPhone or iPad - Apple Support


Just to make sure you cover all your bases, we recommend that you check for a carrier settings update and connect with your carrier to confirm expected coverage and any potential issues with your account or network.


Check for a Carrier Settings update
To manually check for and install a carrier settings update:
1. Make sure that your device is connected to a Wi-Fi or cellular network.
2. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.
3. To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier.
If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.

If you're still experiencing issues with your cellular data connection and loading content, connect with Apple Support over the phone. They will typically have the best tools and resources to troubleshoot an issue with one of their products. You can set up a call from the Get Support portal in most countries.


Kindest Regards.

I’m having the same issue on my brand new 15 Pro.

I upgraded from the X, and had the same issues on it but thought the upgrade would help. Nope. Still showing 1-2 bars on the LTE network instead of 5G. I’ve checked all my settings as per this forum. I have not attempted an eSIM yet as it seems only some people are having success.

Right beside me my husband has full bars on his Android. I’m on an offshoot of the same provider as him but they insist they do not throttle (in fact say that it is not possible to) so I am technically on the exact same provider.

Is this a problem then with the 15 itself? Should I have bought a 13 or 14 instead? I thought newer would be better.

I have Apple everything so stuck with it as it all syncs together but this is making me think about my next purchase. Might be switching to android.
