SIM SUDDENLY STOPPED WORKING
I bought 2 SIMS, 1 worked fine the other stopped working after 9 days and getting a response from King Sims was painful and the problem not solved. Waste of money

Easy and great service
Great coverage, nil issues when using

Hit and Miss
Worked for some texts only and found it really disappointing. Data was very fast though compared to Australia. Would not use it again though, not reliable enough and was I left stranded a couple of times without being able to contact my travel companions.

King sims
Great did not have any problems activated straight away.
