I'm on an LG Nexus 5X, and it's approximately 18 months old. I've been noticing some text messages are not being received on my end. I can make calls and send text messages consistently, but there have been some messages that I have not received from friends and family. The messages have been MMS and SMS, they've come from people with iPhones and Android phones, and multiple different messaging apps. And there's no pattern I can discern to what causes these missed messages, so I can't replicate whatever is causing my phone not to receive sporadic texts.
Has anyone had a similar experience? Could it be the SIM card? That is particularly old (probably 6-7 years old), it's been swapped from multiple phones up til now. Or should I just suck it up and do a factory reset?
