why does my phone duplicate sent texts several times?
What texting app are you using?
Messaging and it is happening off and On. Not all the time.
Try a different texting app, like Verizon messages since it uses the same signal for texting...unlike WhatsApp or others that use the data signal. If it continues, it may be the SIM card, and if not, it may be the app itself. You can clear the data/cache in the app manager in phone settings.
Thanks. I will try these suggestions.
