*556# does double duty on STC Kuwait — the same code that checks your data balance also lets you browse and activate new packages, which is different from a purely read-only balance check.
Quick answer
Dial *556# to browse and activate data packages, or use the MySTC KW app for the full catalog with visual pricing.
One code, two purposes
Unlike *555# (general balance only), *556# is specifically the data-services menu — meaning it’s built for both checking and subscribing in the same session, rather than requiring a separate activation step elsewhere.
Package types
- Daily / weekly / monthly bundles
- Social media unlimited packages
Before you subscribe
Recharge first via *500*PIN# if your balance is low — see recharging STC Kuwait.
