Morning, still no signal

chrisco_4148689​ Firstly, log in and check that your Account Dashboard shows an active sim and a current Smarty plan:

Next, do a Coverage check to ensure that you should expect a signal where you are:

Next, do a Network Status check to look for any local mast issues -

It may be worth putting your sim in another phone if possible to exclude phone issues.

Once you have tried all that, a web chat with Smarty Support is your next step: http://www.smarty.co.uk/contact
