T-Mobile plan huge non-EU roaming price hikes

At the same time as everyone was talking about the proposed merger/joint venture between T-Mobile and Orange, news was coming out about a series of eye-watering price hikes for users roaming outside the EU, taking effect in late October.
With the EU introducing price capping on voice, text and data charges when roaming within member states, What Mobile has become used to the fact that roaming costs outside the EU are usually increased to compensate.
T-Mobile has now jumped on the price-increase bandwagon, with new costs that take effect from the 26th of October.
Calls made or received in Andorra, Faroe Islands or Switzerland will rise from 55p to £1 per minute.
USA, Canada, Australia and New Zealand will rise from between 55-75p per minute to a new cost of £1.20 per minute.
Other countries, with charges ranging from £1.30-£1.40 per minute will rise to £1.50 per minute.
