Phones: Movistar/personal/claro?

[Alicia karr]

I'm using iPhone 5, purchased unlocked inUS and can usually only access internet where there is WIFI , but sometimes with a lot of patience I can get 3G. Oddly my email and messages come without much proble. I use a Plan thru Personal...in recoleta there's good reception.

It's an iPhone 5 Model A1533. According to Apple's website it's a GSM model. I've used iPhone 3 and 4, always GSM, here in Buenos Aire with internet signal problems. My friend has a Blackberry and is always connected to the internet and my other friend with a Samsung doesn't have any problems either.

Ah ok, it's a 5s. No matter.
thanks!

I think all the iphone CDMA models include GSM as well by the way - and the 5s is even more confusing in that the CDMA and GSM models actually share a model number - A1533 - what you get depends on where you bought it. But, no matter, it's likely not your issue.
