Why can’t I access any International networks while Data Roaming is enabled?

You may not have international access enabled on your account. You can usually enable it via your account online, or by contacting your wireless provider.

How do I know when I’m roaming?

A small triangle icon or the letter “R” will appear above the signal strength indicator bars to indicate when you are roaming.

Will this setting affect phone calls?

No. The Data Roaming setting only deals with the connection to the data network. It has nothing to do with the voice network.

Will this setting affect SMS text messages?

No. However, you can set your phone to receive text messages while roaming by opening the “Messaging” app, then selecting “Menu” > “Settings“, then selecting the “Roaming auto retrieve” setting.

    How can I block certain carriers while roaming? As an example, while on a cruise ship, I don’t ever want to connect to MCN (Maritime Communications etc.), as they charge a fortune for roaming, even though I could reach my local T-Mobile account for no-charge roaming. I want to block MCN only, as the other carriers are at no extra charge with T-Mobile.

    Suggestions appreciated.
