Firstly I want to say about the networkThe signal of these sim is to poorI am using these sim since one year but when ever i’ll go in some homes the signal will get decline and I will not get any calls untill I came out from the house and restart my mobileCustomer service was also not good because when ever I will call to the customer care the line will be busy and some operators will disconnect my callThey are charging more money for the smsBefore these it was not like thatU need to improve your signal strength and negiot the prices of the sms’s
