You know, we are now faced with the fact that when selling some SIM cards sharpened (oddly enough) for voice communication (I do not understand how this can be but this is the explanation from the seller), so these SIM cards were altered to a rate below the Internet.
After that, the SIM seems to work, the network sees and all that but in an Internet did not go well as.
As it turned out, there is a difference, I suspect the presence or absence of any pre-settings.
In short, the seller changed us so two in a row and they did not work then finally found something that made all of this was with a Megaphone.
What am I?
To what likely is coming to operator in the office and replace the SIM card.
