Which phone carrier has best coverage in metros/trains?
i have llamaya sim card (prepaid) .
lately it is giving me very bad reception especially when in the metro or trains.
what is bothering me is that it isn't always like that, bad reception just lasts few days or two weeks and then back to somewhat normal. every now and then i get periods of very bad reception and now i am fed up with them.
I am looking to switch to a company that provides good internet on the phone while commuting (i spend big chunk of my life commuting) so i am willing to spend on a contract or pay more if good coverage is guaranteed
also i am not sure but i heard that low cost sim cards and especially prepaid get poorer internet because they are given lower priority when there is congestion in the tower. can anyone confirm if this is true
