30-day business mobile phone contracts

The mobile phone industry is an unnecessarily complex world. To introduce some sanity, we've put together a range of simple, no-nonsense tariffs on 30-day rolling contracts that get billed alongside your Cobalt monthly telephone bill. All of our tariffs include calls, texts and data to the UK and EU (a 20GB data limit applies while roaming in the EU).

A tariff optimiser that works for you

Many people don't know how much data they need and always go for the unlimited option when they don't need to. For just £1.50 per SIM, per month, we'll review your usage at the end of each month and invoice you for the right tariff. So if you're normally on the 4GB bundle and suddenly use 20GB in one month, we won't charge you for the extra at £10 per GB — instead we simply move you to the 20GB bundle for that one month at just £3 extra.

SIMs and handsets, separated

We've purposefully separated the SIMs from the mobile handsets. It's always cheaper to buy them separately and, as handsets last much longer these days, it lets us keep all our SIM deals on a 30-day rolling contract. If you need phones, we can provide both purchase or 2-year rental options.
