Why can't I call or text after activating?

In some cases activation may take up to 2 hours to complete. 

Don't forget to configure your APN parameters https://fizz.ca/en/faq/what-are-fizz-network-settings-apn

Turn your phone off for 5 minutes, and try again

As others said it could take up to 2 hours to get the transfer done. Fizz support is over chat only.

Check at your apn settings. Worked fine for me.

Mine only took 15 minutes from activation but I was on Videotron so that's maybe why. It can take a while though depending on several factors.

It depends on your plan. Do you have minutes ?

Also, if you are on iPhone, update to the latest firmware.

download the 3u tool so you will be able to force flash any firmware and also give jailbreak on any devices men

In 2 of my plans, it's half activated, you need ask Fizz to do he activation manually . Contact Fizz and ask their 'special' team involved.

Can take a few hours before your full service works

Wait , and if nothing contact Fizz to confirm the activation is complete correctly
