My phone is showing E instead of 4G

Hey there, Hele55,

Thanks so much for using Apple Support Communities. We want to help make sure you're getting the strongest signal you can.

There are a couple things you can try on your iPhone but ultimately, your cell signal is something that you'll want to discuss with your cell service provider. They are going to be the experts in their network, so they should definitely be your first stop to getting this squared away.

For now, though, there are some steps you can try on your iPhone.

• Here is an article that you can use to help you navigate your settings to see if switching something up there may get you a stronger signal: View or change cellular data settings on iPhone - Apple Support
• If you're ever seeing "No Service" or "Searching" instead of that "E" symbol, than this article may be helpful as well: If you see No Service, Searching, or SOS on your iPhone or iPad - Apple Support

We hope that this information is helpful.

​Have a great day!
