RoamingAdvisor.com is the only independent mobile roaming cost comparison engine on the internet. We help business and leisure travellers cut costs when using mobile roaming to make and receive both local and international calls.

RoamingAdvisor.com was a little project we built to help frequent travels safe on their mobile and data roaming costs. We travel a lot ourselves and we that operators don't always offer the best rates. More than a few times, we were very surprised to return home and find hefty data and mobile roaming charges added to our monthly tariff. RoamingAdvisor.com helps you to avoid roaming surcharges by suggesting a number of low-cost, no-commitment travel sim cards to help you cut down roaming charges.

After some early recognition for presenting independent, cost-effective international roaming and mobile roaming options to consumers, we upgraded our system to provide further comparisons and independent reviews of all commercially available mobile roaming SIM cards in the UK. We compare mobile roaming SIM card prices and international roaming charges on both inbound and outbound roaming calls. We make it easy for you to find a travel SIM card that suits your individual travel needs.

The European Union has legislated to reduce roaming call costs within European Union member states, but major network providers in the UK are only reducing their rates by the legally enforced EU minimum. This means you can still benefit from considerable savings if you travel within the EU and regularly use data roaming or mobile roaming, even for short periods. EU legislation does not apply outside of Europe, where roaming call costs can still exceed £1 per/min.

At Roaming Advisor we compare the latest international roaming tariffs and international mobile roaming charges for global mobile roaming SIM cards and European SIM cards.

We provide international roaming rates based on the current currency value, as the exchange rate fluctuates; some UK based providers have become cheaper because the Sterling has lost value. This has lead to cheaper mobile roaming charges on travel sim cards from UK service providers.

Provide accurate inbound calls rates, i.e list their services and where the call originates, some 07 numbers for mobile broadband where based on expensive mobile numbers in isle of Mann or Jersey and some providers have travel sim cards with Estonian numbers, which means when your friends or colleagues call your mobile roaming number, they could be the ones paying expensive tariffs to call you. We recommend you check and, depending on your mobile roaming needs, defer paying for received calls when you are abroad.
