MMS; Message Failed to Send; Receive Old Texts Randomly

I have frequent problems with sending group texts while at home. I get frequent “message failed to send” alerts, and it takes multiple attempts for the message to get through. I also will receive texts in group messages late. My phone will sometimes receive messages that are clearly several hours or even days old, often in large groups. Sometimes, I’ll receive 20-30 messages at once.

My AT&T network signal at home is very spotty, 0-1 bars. However, I have excellent wifi. I have WiFi Calling enabled, and I have no trouble making or receiving phone calls. iMessages work with no problems. It is only with SMS and especially MMS messages, which I thought were also supposed to work over WiFi calling.

I have an iPhone 11 with AT&T.

I have the latest software. For everything.

WiFi Calling, Send as SMS, MMS Messaging, and Group Messaging are all turned on.

I have tried turning these off and back on again.

I have tried turning off cellular and turning it back on again.

Thanks again.

SMS and MMS require a cellular signal. SMS will generally send even if the signal is weak but it does need something. MMS requires more bandwidth. Having WiFi calling enabled won't help. You might want to talk to AT&T to see if they offer any options to improve the cell signal in your house.
