I have an iPad with cellular capacity. I had it stuck to tight in my bag one time that i was not able to receive messages. I thought I got it broken! bought it just a week... Pero hindi... eto palang Smart ang engot!!!! Pati yung sun at times you can't receive messages. I tried using my sim to another mobile tos ganun parin Ba't ba lage nalang down yung satellite ng smart at sun?
