Vodafone’s Summer promo started yesterday, so now Vodafone customers can enjoy roaming phone calls at no extra cost, as long as they’re on Passport. We had a think about how to model this in our system and we decided that if we removed the 75p cost per call, you’d get stung when September came along and the cost was added again. Therefore, the prices shown in BillMonitor continue to reflect the full cost.

This promotion is an excellent deal for the Summer, and we hope that lots of our customers can save money with it, but we don’t want you to sign up for a contract that’s going to work out more expensive for you in the long run.

In summary, Vodafone Passport customers (And that’s anyone on Vodafone, as long as you opt in to it for free) will be able to use their phone to call and text the UK for the same prices as at home in 35 countries across Europe. As long as you’re calling back home, the free minutes and texts from your plan will apply. This all kicks in on the 1st June and runs through to the end of August.

On top of that, international calls will fall to as little as 5p per minute for pay as you go users from 15th May.

This is sure to leave most networks in the dust for big international users. Will any other networks step forward and attempt to compete?
