Hello,
I’m currently using the EG91NAFBR module with a Verizon SIM card. I’m having a problem with text message sending. I checked at+qcfg=“ims” and found that IMS registration sometimes fails. After activating and re-registering, it works fine, but it’s very unstable
Do you have a newer firmware? I’d like to upgrade to a newer version to see if it’s stable. My current version is EG91NAFBR05A04M4G01.004.01.004. Could you send me the latest firmware?
