We just told you how MetroPCS intends to increase business by offering revised service plans and additional features in each plan (click here for original post). Competition everywhere is pretty high. So now, both Virgin and Tesco Mobile in the UK are going ‘unlimited’ with their tariff plans too.

Virgin Media have lifted the curtains off their £65/month tariff, which comes with unlimited call, text and mobile Internet usage. The problem is that you have to sign an 18-month contract. This service does not include the Samsung Jet, Nokia N86 and some other devices. Well, that seems to be a very long-standing contract and not really too inexpensive, so we have to see if this will be as popular as the company expects it to be.

Next comes Tesco Mobile, which has also introduced its new ‘unlimited’ tariff plan. It offers a pay-per-month contract at a mere £30/month. In addition to this, this service is SIM-only, which means, you need to get your own device. This tariff is basically talk and text only. So this is a great idea if you only message and make a lot of domestic calls. But if you are used to making international calls or browsing the Net on your phone, this tariff plan is clearly not for you. Click here to know more about Tesco Mobile.

Zer01 Mobile has officially announced its new Zer01 Mobile true unlimited voice and data mobile service at the CTIA Wireless 2009. This service is priced at $69.95 per month without contracts and will be on from July 1, 2009.

Treating all phone calls as data packet, the company routes all phone calls with its proprietary VoIP system. This process requires a software to be installed on the phone that can handle a secure connection between the user’s phone and Zer01 backend servers. The Zer01 Mobile unlimited service will initially be available on Windows Mobile smartphones. Support for other devices such as Blackberry, Android and iPhone will be available within a few months’ time.
