Activate Indosat M2 for Free Nighttime Internet
Indosat M2 was a legacy prepaid data package designed for browsing, messaging, and social media during selected nighttime hours. Activating it normally required sending a short activation message, then configuring the phone to use Indosat’s mobile-data connection.
For Australians, M2 required careful planning because its free window followed Indonesian network time rather than Australian time. It was useful for travellers in Jakarta or Bali, but it did not turn an overseas Indosat SIM into a free roaming connection.
Understanding the M2 Night Bundle
M2 was the package’s name, not an indication that it contained two megabytes of data. The promotional entitlement commonly applied from midnight to 06:00, Indonesian local time, with the precise allowance and eligibility rules determined by the version of the offer available to each subscriber.
The free nighttime data was intended to remain separate from ordinary paid data credit. Standard charges for sending the activation SMS could still apply, so checking Indosat’s current terms prevented an unexpected charge.
Time-zone differences mattered. Perth is one hour ahead of Western Indonesian Time, while Sydney is three hours ahead and daylight-saving changes make Melbourne four hours ahead during summer. A 10 p.m. browsing session in Sydney could therefore fall outside M2’s Indonesian nighttime window.
Activating M2 Through SMS
Open the phone’s messaging application and create a new SMS addressed to 2345. Enter the activation keyword exactly as M2, send it once, and wait for Indosat’s confirmation message. Spacing, extra numbers, or a different keyword could prevent recognition.
After confirmation, check the package status through Indosat’s USSD service, commonly *336# on legacy accounts, and verify the activation time and remaining allowance. If no reply arrives, confirm that the SIM is active, registered, and able to send ordinary messages before trying again.
BlackBerry Curve users may need to complete BlackBerry BIS setup before the handset can establish its mobile-data route. BIS also supports email and BlackBerry services, although the separate M2 activation is still required for the nighttime bundle.
Preparing the Phone for Nighttime Data
Mobile data must be enabled, and any Wi-Fi connection should be switched off during the first test. On an Android phone, iPhone, or BlackBerry, use the Indosat APN supplied with the SIM or shown in activation instructions; incorrect proxy or authentication settings can block data even when M2 is active.
Command-line testing is optional, but a terminal emulator comparison can help users of Linux-based devices choose a tool for checking DNS, connectivity, and network responses. The goal is to confirm that traffic reaches Indosat rather than failing at the device configuration stage.
Once the connection works, open a lightweight website or messaging service and avoid large downloads. Keeping activity modest helps confirm that M2 is active without exhausting its limited promotional allowance during the first session.
Comparing M2 With Other Data Choices
M2 suited users who mainly needed a connection late at night in Indonesia. Regular Indosat data remained more useful for daytime browsing, maps, and video calls, while international roaming could become expensive even when the local promotional window was active.
Sending one activation SMS is different from sending a group message. A guide to multiple SMS on BlackBerry illustrates how queued messages work, but duplicate M2 requests should still be avoided.
Australian prepaid plans from Telstra, Optus, and Vodafone generally price local data in AUD and may include tethering, while Indosat M2 followed its own balance and time-window rules. Australians also use the word “dongle” for USB mobile broadband, so that term should not be confused with an Indosat data-enabled SIM or a compatible smartphone.
| Data option | Best use | Access pattern | Main limitation |
|---|---|---|---|
| Indosat M2 | Overnight browsing and messaging | Free promotional data during the scheduled night window | Indonesian time and account eligibility apply |
| Regular Indosat data | Daytime browsing and larger transfers | Metered GPRS, EDGE, or 3G access | Uses normal credit or a paid data allowance |
| Australian prepaid SIM | Local Australian mobile use | Data charged against an Optus, Telstra, or Vodafone plan | No free Indosat nighttime allowance |
| Travel dongle | Laptop internet access in Australia | USB modem connected to a local prepaid plan | Separate hardware and data charges |
Starting Your Nighttime Data Session
Complete activation while the Indosat SIM has a reliable signal, since the confirmation message establishes the subscription for the relevant account. The following routine keeps the setup predictable:
- Send the keyword
M2to the short code2345exactly once. - Save the confirmation message for reference.
- Check the package status and allowance through Indosat’s USSD menu.
- Confirm that mobile data is enabled and the correct APN is selected.
- Test the connection with Wi-Fi disabled before restarting normal use.
- Schedule downloads within M2’s Indonesian nighttime window and monitor the balance.
Open Messages now, send M2 to 2345, and complete the connection check before leaving your hotel or home in Jakarta or Bali. That small preparation step ensures the free nighttime allowance is ready when the off-peak period begins.
