O2 Reveals Details of 4G Mobile Tariffs

December 12th, 2013

O2 customers broadband 4G tariffs

After much deliberation amid the mobile market, leading operator O2 has finally announced its own concrete plans for the completed roll-out of its highly anticipated 4G service.

Although the service was originally launched back in August this year, it was not yet available to all O2 customers – only those on particular tariffs or within certain locations of the UK. Slowly by surely, O2 has been working to expand its 4G outreach to all cities and customers throughout the UK.

After the original roll out, O2 announced its Pay As You Go 4G plans (excluding mobile broadband) earlier this month, and promised that details of its 4G mobile broadband plans would soon follow.

Indeed they have – O2 customers can choose between a Pay As You Go mobile broadband package, and a monthly contract mobile broadband package. The latter does not involve any long term commitments, such as early-leave fees, should customers wish to change or upgrade their contract when it is partway through.

The Pay As You Go package entitles customers to 5GB of 4G data for up to 90 days for a one-off price of £30. The Pay Monthly plan, meanwhile, will either be able to enjoy 3GB of data for £15 or 5GB data for £25. Unused data can be carried forward, although customers can be charged £10 per GB for going over their allotted usage.

As far as hardware goes, customers will have a choice of either a USB dongle or a WiFi device with which to enjoy their 4G broadband.

Number Direct is a telephone directory and call routing service and is not connected to O2 . The direct contact number for O2 can be found in the public domain or on their official website.
