Becareful when roaming overseas

When u go overseas, the incoming charge, outgoing charge and data charge are quite expensive. (per min basis)

incoming charge is how much singapore calls to your location eg 70 cents

outgoing could be either local 50 cents , singapore 60 cents or overseas. Currently overseas outgoing via smart roam is the cheaper option becos u need to pay the location to singapore charge 70 cents ( usually same rate with incoming call) and then a zonal charge xx cents. If you do a outgoing direct overseas it will cost a flat rate of $4

So think twice. Data is more expensive on a per MB basis unless a flat rate per day is applicable otherwise it could cost a bomb.

Singtel recently came out with a travel SIM which gives u 2 number overseas and singapore number on the same sim. whether your caller is local or overseas there are no roaming charge for u or the caller. But there is a monthly charge of 10 dollar per number but receiving calls is practically free

location sin -> sin caller local rate ; overseas caller local rate (via overseas number)
location overseas -> sin caller local rate via sin number ;overseas caller local rate
