I don't think the cards from www.himtel.com are such bad....all the low rates cards of $2 and $5(which give about 25 minutes and more than an hour respectively in KTM) usually have no problems at all but sometimes may have problems during peak hour.Nonetheless,the respective customer support of the cards help in the matter........................................AND HIMTEL AFAINLE PANI MILCHA VANE CARD HERPHER GARIDINCHA NAVAYA RESPECTIVE CUSOTMER  SUPPORT TA HELPFUL NAI CHA NI HAINA RA???????????????????????

ra himtel ko afnai card himtel use garema no problem at all....ahile $10 ko 31 minutes dincha ra it's very very reliable....no connection fees and no maintenance fees..ablsolutely fine .....very clear sound quality........

ra if we buy from the stores there's no one to complain if we have problems....thus it's just waste of $$$$$$.....
