The idea of the 'whack-a-mole' game is that each time a mole's head appears above the parapet, you clobber it with a hammer and push it back down, the goal being to keep the playing field clear of moles. But no matter how hard you hit a mole, there always seems to be another one willing to risk being whacked.

Keeping your mobile phone bill down is very similar to a game of whack-a-mole. Just as you think that one set of charges has been reduced, some new charges pop-up somewhere else. And so it is with the abolishment of roaming fees in Europe. No longer will you have to pay any more than your standard fees for using your standard call package when travelling within the 28 European Union Member States. Remember though, this only applies to calling and texting home, and to using data. If you want to make a call to the restaurant down the road whilst you are staying in France, this is still an international call from the UK. So which mole is sticking its head above the parapet now?

Prior to the abolition of roaming fees, several mobile operators offered roaming packages which were designed to help travellers keep down the cost of roaming. Take Vodafone as an example. For those travelling to the EU 28, it had a package called 'EuroTraveller' which allowed you to use your home allowances for GBP3 per day. There was a secondary package called 'WorldTraveller' which allowed you to use your home allowances for GBP5 per day in another 60 or so countries. Both of these packages were optional and you could opt in and out willy-nilly. So if you didn't want to use your packaged in full, but just wished to send one text message, you could opt out (ideally before you travelled) and just pay the 30p or so rate for a text instead of GBP3, meaning that low users and high users could select a deal that was best for them.

So as of June 15 when EU roaming is free, Vodafone has introduced two new packages, 'Roam-Free' and Roam-Further'. Roam-Free allows you to use your UK package in the EU28 plus a few non EU-countries such as Iceland, Norway, Switzerland and Turkey at no additional charge. Roam-Further allows you to use your UK package in a further 60 countries (largely the same as the previous WorldTraveller package excluding, for some reason, the United Arab Emirates) for GBP5 per day. So it sounds the same, right? Wrong! The Roam-Further package is NOT optional. This means that if you travel to one of the 60 countries included in the list, such as Australia, Hong Kong, Thailand or the USA, and send a single text message to let someone back home know that you are OK, it will cost you GBP5. There is no way to opt-out of this package. So instead of costing 35p for that text, it will cost GBP5. And there's your new mole, peering out of its hole.

Just when you thought that roaming was going to be cheaper and easier, if you travel anywhere outside of the EU, the operators will now try and recoup their costs from you by charging more for roaming than they did before. Of course if you're a heavy user, not much has changed, but for most holidaymakers who just want to let someone back home know that they are OK, and use WiFi to upload their holiday snaps to Facebook, that little text has become a whole lot more expensive.
