data settings on BLU LTE

Hello

I've just bought a BLU 5.0 LTE unlocked phone from amazon.ca to use with my FIDO sim card. Unfortunately it seems the data connection does not work, while in theory it should. does it require any particular setting of the "access point names"?

My phone phone operates in these bands

GSM: 850/900/1800/1900

3G: UMTS 850/1700/1900/2100

4G: LTE 1700/2600

for the rest it works perfectly, but if the internet does not work I will change the operator.

thanks for clarifications!
