STC gives you two genuinely different ways to check your bill — a USSD code for a quick figure, or an SMS shortcode that arrives as a message you can keep for reference — and either one answers the same question depending on which format suits you.
Quick answer
Dial *166# for an instant on-screen summary, or send “1112” to 900 for the same information delivered as a text you can refer back to later.
Choosing between the two methods
| Method | Best for |
|---|---|
| *166# | An instant on-screen check, no record kept |
| SMS “1112” to 900 | A saved text you can reference again without re-checking |
MySTC app for the full picture
Neither quick method breaks down individual charges — the MySTC app → Billing section shows itemised usage, payment history, and your exact due date, which matters if the total looks higher than expected and you need to see why.
Paying and avoiding late fees
Set up SADAD auto-pay in the MySTC app so your bill is deducted automatically from your bank account, and consider paperless billing while you’re there.
