Truphone's 'upgrade' seems to involve a loss of key functionality...
got an email today with this:
"If you have additional mobile numbers associated with your account and you would like to keep these you need to enable auto-renew within your Truphone account or you will lose the number permanently. To do this, simply log into ‘My Account’ via the Truphone website (
Truphone), select ‘Manage Upgrades’ and ensure ‘Auto Renew’ is set to on."
For me, an important feature was the ability to switch on a UK (or Australian) number for just a month when I travel for $8, and then turn off auto-renew again. Now we'll lose the UK number, unless we pay EVERY month. I suppose we can live with a different number each time we travel, if that is possible, but it makes Piranha look more enticing.
