​@Sufyan Ul-Haq  Depending on how long you've been with IDMobile there's  a cooling off period. In most cases one has to give a 30 day notice of cancellation and pay any outstanding cost.

No network if perfect they all have their limitations, have you checked your postal code if there's any issues or maintenance work being carried out? Sometime it can be down to the handset with substandard communications radio chip's, Samsung was know to have such a problem and continued to fit these in their device's.
