Hello Zillyness233,
Welcome to the community!
Firstly, you should note these forums are community-driven and not intended as a venue for customer services. We do not have access to all offers and promotions available to potential customers.
That said, I'm not sure whether Fido will be able to offer the same plan you have with Rogers. I have not seen any offers on Fido.ca which include calling or roaming in Mexico. In addition, it should be noted that Fido does not currently offer 5G services (see here). Furthermore, I don't believe any of Fido's plans include Infinite offerings. As far as I am aware, all of Fido's Data plans include an allotment of data. Once that allotment is used, additional data may be purchased for further usage.
If you would like to discuss your options, you would need to contact customer service. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
