Getting text alert but no message?

[Meonia]

Hi. Pretty much every day I'm getting a text alert going off but when I check my phone I've not received a message of any sort. This happens usually once in a day but sometimes twice. I've no idea what's causing it and wondered if anyone has an explanation/solution? I've only had the phone for a couple of weeks and I've not set anything that might generate an alert (reminders, alarm, delivery reports), so I'm stumped!

I suppose you receive notifications from a game. It's like a message, reminder about current deal, offer etc. I simply disable it by deleteing that game.
