Can't call

Hey  YuqingL_2701337,

There are a few reasons this might be so if you do still need help our customer support team are on hand https://smarty.co.uk/contact available daily from 8am – 8pm.

YuqingL_2701337  As well as what JJP2RidesAgain  says, it may depend upon when you activated the sim and purchased the plan. You sometimes need to wait a little while≥

Also may help to turn phone off and then on to force sim to register to network.

In addition, do a Coverage check and a  Network Status check to ensure that there is no local problem.

Do you have an active plan ? 

Check your Smarty account dashboard or app, to make sure your SIM had actually been activated and you have bought a plan.
