I've had two people that regularly text me say that I've not received their text messages. Both of them, and myself, are on Vodafone and our phone numbers have only ever been on Vodafone (eg. we haven't ported them from another provider). All the phones are Android.
Both people have shown me their phones and the missing messages, with a sent date/time, and I've checked that I have no messages on my phone from them that match.
The issue seems to be intermittent, whenever these people have complained I've asked them to send a message while I'm standing there and the messages always come through (much to their annoyance!)
Does Vodafone provide a log of text messages somewhere that I can check to see if VF thinks it sent the message on to my phone or something like that?
I know text messages are old fashioned and most people would suggest that I just use a messaging app, but I only receive text messages from a few people and don't want to waste the space on my phone for an app that might only get used a few times a week.
