Hi there,

I've been having an on-going issue with Vodafone since September last year. The problem I have is that in low 4G reception; my phone (used to be an S4 now a Note 4, it happens on both) doesn't send SMS until it then changes down to HSPA+ or 3G but often doesn't do this until the messages have failed, usually multiple times. From what I understand this shouldn't be happening because SMS don't require a handoff like phone calls, in fact if I turn my phone into 4G only or 3G the problem is eliminated but each with its own problems.

These failed messages apparently do not show up on Vodafone's server and they therefore cannot prove the problem exists. There are sporadic forum posts on the internet about this problem happening but never a solution, usually always because the telco can't locate the problem.

I've kept logs, changed sims, obviously its happens on 2 different handsets, tried different apps (a point of contention), tried logcats all to no avail.

So i'm appealing on here to see if anyone else has this problem, if they do maybe I can persuade Vodafone to do something about it. If you can please help.
