STC FAQs

You’ve got questions, we’ve got answers!

Can I get STC Mobile if I don't have Sharon Internet?

Can I bring my own device to STC Mobile?

With STC Mobile, you can keep the device you love when you switch as long as the phone is unlocked and compatible with our network. To find out, locate your device’s IMEI number in your device settings, then select ‘Bring Your Own Device’ from our mobile shop page. Enter your device’s IMEI number to see if it’s compatible with our network.

Are there any contracts or long-term commitments with STC's mobile plans?

We offer flexible plans without long-term contracts, allowing you to choose options that suit your needs. You can switch plans or cancel at any time.

What happens if I exceed my 1 GB on the By the Gig Plan?

With our By the Gig Plan, you do not have a monthly gig limit. Instead, you are charged for each gig you use at $15/GB. Portions of Gigs used are not prorated; for example, if you use 1.5 GB of data, you will be charged for 2 GB. We will send alerts as you near/exceed each Gig.

Our customer service is rooted in hometown values, providing personalized support to ensure a smooth mobile experience. Our goal is to be your lifelong broadband and communications provider.
