Alternatives to Traditional Calling
For frequent Indonesia communication, consider these options:
WhatsApp Voice/Video Calls
Free calls over internet when both parties have the app. Quality depends on connection speed. Most Indonesians use WhatsApp as their primary messaging platform — it's extremely popular throughout the country.
Browser-Based Calling
Call any Indonesian phone number directly from your browser — mobiles and landlines. The recipient answers on their regular phone, no app needed on their end. Benefits:
For travellers, international SIMs sometimes offer better rates to specific countries. Evaluate based on your call patterns.
VoIP Services
Services like Skype credit or similar platforms offer international calling at reduced rates. Per-minute costs vary by service.
Saving Indonesian Contacts Correctly
For seamless dialling regardless of your location:
Save numbers in international format:
plain text
+62 812 3456 7890
This format works whether you're in the UK, travelling abroad, or even visiting Indonesia.
Avoid saving as:
plain text
00 62 812 3456 7890
The "00" prefix only works from the UK and some European countries.
Don't save the domestic format:
plain text
0812 3456 7890
This only works when physically in Indonesia.
Calling Bali: A Common UK Destination
Bali receives significant UK tourist traffic. If you're calling Bali contacts:
Bali mobile numbers: Follow standard mobile format
plain text
+62-812-XXXX-XXXX (or any mobile prefix)
Bali landlines: Use area code 361
plain text
+62-361-XXX-XXXX
Hotels and businesses: Most publish international-format numbers on their websites. If they list a domestic number like (0361) 123456, dial:
plain text
+62-361-123456
