Ask for help: Indonesia's indosat how to check the phone bill balance by SMS, and can't understand Indonesian when calling.

C users of China Telecom and G users of China Mobile can roam internationally in Indonesia. However, the C network has no signal in Batulisin in East Kalimantan and South Kalimantan. Therefore, it is necessary for China travelers to buy a local calling card, both in terms of cost and communication smoothness. I chose SimPATI card of TELKOMSEL. This kind of calling card and its supporting recharge card can be seen everywhere in business halls, street vendors, convenience stores and even hotels/guesthouses.

After the new card is loaded into the machine, there must be steps to open the card and register it. It doesn't matter if you can't operate. The card seller can do it for you. After registration, you can use this number.

There is no roaming charge for mobile communication in Indonesia. The rates for calling landlines and mobile phones all over the country are the same, and answering is free. The rate is very low, so don't worry too much. If you want to query the balance, just dial *888# to automatically display the balance. When making an international call, it will be very expensive if you dial directly. Prepaid card with face value of Rp 10/00000 (about 1 1 USD) will be reimbursed in a few minutes. But if you add the prefix "0 10 17" or "01kloc-0/9", the phone bill will be almost as cheap as the local call. I'm too lazy to ask about the specific rate, but according to my mainland compatriots living in Indonesia, the international long-distance call charge is even lower than that in Indonesia.

In addition, Indonesia's mobile communication has entered the 3G era. Judging from the limited English words in the SimPATI card manual, they have opened many services, such as video calling, mobile TV, mobile video, video conference, video message and so on.
