3G Mobile Broadband Blocked Ports and IP Assignments

3G Blocked Ports Please check the table below to see if your preferred 3G provider is blocking any IP ports that you may require. All information has been collected direct from the providers.

If you don't understand the blocked ports numbers, look at the 'Allowed IP Ports / Applications' column, which lists the most common types - for example FTP & VPN support. Please check the main comparison table for Skype support, as support for this feature can vary from the same provider depending on the tariff selected.
