Mikael's standard sms top up calling service has been very great and excellent service from 2008 to 2010.it has been the best service to make international calls.if that service resume again,than I think there shall be no need of any service.
currently following services are operating to make international calls.
1.Mikael's services:
03 topup calling service
PAYG mobile international calling service
skype topup calling service
2.davegr's call through service
3.pre caller topup calling service
4.pre caller sms topup service.
5.cheap to dial calling service.
all of the above services uses unlimited landlines and unlimited text packages.except PAYG service.
due to strict changes in different mobile phone network policies in 2010,any new service like SMS topup calling service, shall not last longer.
Great summary.
just went into precaller: calling a 03 access number for 2 minutes gains 1 credit; thus, is precaller not a better and faster option to gain credits as compared to mikael's 03 topup service???
