I used postpaid visa platinum offer sim for Thailand
Its reasonable and good service provider, but an effort is required to fully understand the offer provided by them as the leaflets are not comprehensive.
Customer care is more responsive on telephone numbers and almost no response through direct e-mails.
They charged me extra for data use, which when I told them that I have never used, they were prompt to correct the bill for me.
Details are not very clearly or prominently mentioned but services and charges are very reasonable
I would like to use it again, as I am overall satisfied.
