+62 881, 882, 887, 888 and 889 numbers: Smartfren mobile lines

A number starting +62 881, 882, 887, 888 or 889 is an Indonesian Smartfren mobile number. Smartfren is now a brand of PT XLSMART Telecom Sejahtera Tbk after its April 2025 merger with XL Axiata, and Indonesia has no number portability, so the prefix still identifies Smartfren.

What these numbers look like

From abroad: +62 881 XXXX XXXX
Inside Indonesia: 0881-XXXX-XXXX

Drop the leading 0 from abroad. Smartfren's own customer service line also starts 0881, so an 088x number in a message is not proof the sender is or is not Smartfren.

Who is calling you from a Smartfren (+62 881-889) number?

Smartfren numbers are common for mobile internet and as second SIMs, so an 088x contact is often a regular person or a small business using a cheap secondary line. As with any Indonesian prefix, a stranger's message offering paid online tasks, a job abroad or a prize, or sending an app file, should be treated as a likely scam.
