Samsung Galaxy Note 3 texting lags with default app
I'm new to this, but curious if anyone else has had or is having lag issues when sending texts? I'd say out of 5 I send, 2 go quickly, the others 2-3 minutes. My husband did a complete reset on my phone, it is also updated to the most current software, I just got the SIM card replaced in case, still lags though, this started happening 2 1/2 weeks ago, I've talked to 8 different AT&T people, all towers in my area 100% working strongly, my friends who have AT&T at their provider have no issues with texting, I have done SO many difrerent steps per the reps I've talked to on the phone or online, and now they have filed a case for me. I am at "Tier 1" for support dept., supposed to have this resolved Friday, but I'm not too optimistic at this point.
Any info., or tips regarding this issue, I would greatly appreciate them
