• Cost of local calls when roaming
• Roaming Sim card price
• Initial mobile roaming credit
• Where the mobile number on your roaming Sim originates
• The international calling prefix for receiving calls
• Mobile data roaming charges

All this information is available for you, free of charge. So how do we make money? RoamingSims.com promotes products from leading world sim card suppliers, and we get a small commission whenever a sim, or product, is purchased.

RoamingSims does not favour any cheap travel sim card provider more than others. Our mobile roaming sim and data sim card comparison is an unbiased comparison. We are in contact with global sim card providers and they supply us with information not widely available to the public. This helps us make sure we offer accurate and updated international roaming industry information. However, these relations are independent of our reviews and they do not affect our reviews.

Please note that we are unable to take responsibility for correctness of the prices posted. Prices posted are based on information from operators and mobile roaming providers. We are not always immediately informed by cheap travel sim card providers about price changes. Conversions from international currencies are done to the same exchange rate. All prices are calculated with VAT.

Please note that following the purchase of a world sim card additional charges may occur, such as:

• VAT
• Delivery costs
• Call set up charges
• Call credit can expire

Re strongly recommend you read all fine print before purchasing global sim cards. We do not promote suppliers that deceive or mislead the buyer, but it is your responsibility to know all the conditions of use. We always try to highlight any issues we think you need to be aware of.
