Since 2013, the CRTC wireless code has included a $100 charge cap on roaming fees. This cap affects pre-and post-paid subscribers to mobile network carrier services. Since Roam Mobility is a prepaid, unlimited service, the CRTC cap does not apply to users on Roam's network.
This cap gives cell phone users travelling abroad the ability to cap their bill when it hits $100 in data roaming charges, rather than just continuing to rack up additional fees. While the new cap will help minimize cellphone bill shock, it doesn't do anything to make USA roaming rates any more affordable.
When the data roaming cap is reached, service providers must suspend additional charges, but may also suspend data services altogether. This means roaming phone-users could be left without mobile data for the remainder of their trip unless they consent to pay the additional charges.
Note: the new cap only applies to data overage charges so customers can still rack up talk and text usage fees while they’re outside the country. With USA roaming rates as high as $1.50 a minute and $0.75 per text message from certain carriers, these charges can still add up quite quickly.
