Here's how you'll get charged for making or receiving these calls. While abroad, the operator you're roaming with keeps a record of your calls, and later shares these call records with stc. Charges are then calculated and reflected on your next bill.

Please also note the below:

1- Roaming rates are subject to change without prior notice.
2- Roaming rates are subject to exchange rate fluctuations and foreign taxes.
3- International call rates while roaming are ordinarily high compared to call back to Bahrain rates.
4- Roaming charges can take up to 3 months to appear on bills. Roaming charges do not reflect in real-time, which means you can't rely on your Credit Limit kicking in and suspending your account to prevent extra usage.
