Prepaid SAWA vs. Postpaid Mofawtar: Key Differences in Checking Data

STC offers two main types of mobile subscriptions: Prepaid (SAWA) and Postpaid (Mofawtar). Checking data usage differs slightly between these categories.

Prepaid SAWA Lines

Prepaid subscribers pay in advance for data bundles. When your SAWA data bundle runs out, your internet access stops completely unless you purchase an add-on or renew your bundle.

• Primary code for SAWA internet check: *8885# or send 2220 to 900.
• Real-time deduction: MBs decrease dynamically as you browse, download, or stream content.
• Validity: Every prepaid package carries a fixed validity period (e.g., 1 day, 7 days, 30 days, or 90 days).

Postpaid Mofawtar Lines

Postpaid customers pay a monthly subscription fee on a fixed billing date. Many Mofawtar plans feature high data allowances or unlimited internet options.

• Primary code for Postpaid usage check: Send 2220 or 4000 to 900.
• Bill summary code: Dial *166# or send 1100 to 900 to receive current bill details.
• Fair Usage Policy (FUP): If you hold an unlimited plan, monitor whether your daily high-speed quota has exceeded threshold speed limits.

Troubleshooting: What to Do If the STC MB Check Code Fails

Occasionally, dialing *8885# or sending an SMS to 900 might result in an error message or non-responsive screen. Here are simple solutions to fix common inquiry errors:

Common Causes and Fixes

1. Network Connection Drops: Switch your phone to Airplane Mode for 10 seconds, then switch it off. Retry dialing *8885# once your phone reconnects to the STC network tower.
2. Incorrect Shortcode Format: Always check that you typed the exact code sequence (asterisk, numbers, hash symbol). Ensure you typed *8885# and not #8885*.
3. System Maintenance: Telecom providers occasionally perform background server updates. If you receive a “Connection problem or invalid MMI code” pop-up, wait 15 minutes before trying again.
4. SMS Delivery Delay: Network congestion can delay text message responses. If code 2220 to 900 does not reply immediately, check the mystc app instead.
5. Incompatible Router SIM: If your SIM card resides inside a Wi-Fi modem, remove it and place it in a smartphone temporarily, or access the router admin panel at 192.168.8.1 to read incoming SMS messages.

Need Customer Support? If dial codes continue to fail, call the official STC Helpline at 900 from any STC line, or dial +966 11 455 5555 from non-STC or international lines.

Practical Tips to Save Your STC MBs and Prevent Overage

Monitoring your balance with an stc mb check code is only half the battle. You should also practice active data saving techniques to stretch your megabytes further throughout the month.

1. Turn Off Background App Refresh

Many mobile applications update content, fetch emails, and refresh feeds in the background without your active knowledge. Go to your phone settings and disable background app refresh for heavy social media and streaming apps.

2. Restrict High-Definition Video Streaming

Streaming video in 4K or 1080p High Definition consumes up to 3 GB of data per hour. Adjust video streaming quality to standard definition (480p or 720p) inside YouTube, Netflix, and TikTok settings.

3. Enable Data Saver Mode

Both iOS and Android operating systems feature built-in Data Saver modes. Turning on Low Data Mode compresses web pages, pauses automatic cloud backups, and stops background app syncing.

4. Set Up Usage Alerts in mystc App

Configure push notifications inside the mystc app. You can set warnings when your remaining data drops below 80%, 90%, and 100% of your total allowance.
