Iphone 4s no service problem?

I'm in Almería spain and my phone suddenly began alternating between searching and no service. I've tried everything and nothing has worked. Please help!

Added (1). I know for a fact my location is not a dead zone because I did have service at one point.

Yoru probably in a dead zone or the towers in your area are having issues… If your spainish, call your carrier… If your american, your screwed.lmao!

Sounds like no service there.
