PTCL Evo on iPad/Tablet

As the title suggests, what would suggest the best option would be to get data on an iPad when I am not at home? I was thinking of getting a PTCL Evo sim and use that. How else you guys out there use for your data connection on tablets or smart phones (assuming Edge is too slow for your normal usage) ?

Thanks in advance for the input guys :)

Get EVO Nitro Cloud or prepaid EVO Wingle with power bank and you will be able to use net whenever you are out of home.
