Disable phone LTE for more reliable texting weak cell signal?

I have the same phone and I think turning off iMessage works

I’ve tried turning off iMessage. Not conclusive.

I’ve been there.

my understanding is that sometimes you’ll see weak signals but they’re not necessarily signals you can use other than for 911.

years ago with an AT&t phone on top of Mount Whitney, I was trying to send a text but couldn’t even with four bars while other people were texting and talking ….

Instead of turning off iMessage, turn off both WiFi and Cellular Data and try that. Don’t turn these off by using Airplane Mode, leave that off. You can turn off MMS too, but not sure that’s necessary if you’re just sending text.

I’ve had such apparently sufficient signals fail to send texts, while phone calls worked perfectly.

Some good tips. Thanks. I’ll try them next time I’m out in Desolation.

Thanks!
