I received an email from James at Callcloud last night saying he was going to be on RPP FM this morning. I listened to the live stream and the code for the promo is FRXRPP. I believe you need to have a Flexiroam account already setup. I added it to my account and got the free 1GB which is valid for 3 days from the date you activate the plan in the app (not 3 days from when you add the code). Plan must be activated before Feb 13, 2020. Not sure how long the code is going to be valid for.
Found out he was also on Flow FM, the code for that promo is FRXFLOW, I've successfully applied both to my Flexiroam account.
Awesome added to my account. Will come in handy next week 👍
