I bought the Samsung S4 less than 30 days ago and several times I send text messages and see that they just "spin" and never get sent. I've rebooted maybe three times since I bought it to correct the issue, I also went on youtube and changed some settings to resolve it.
But this is a real annoyance, because it keeps happening. My darling husband laughs and says he's never had a problem with his IPhone and I got "rooked".
Does anyone have a problem with not being able to send text messages ? It happens sporadically. Some messages go earlier in the day, then some don't later in the day.
