No service this morning?

Hi,
I used the phone, received SMS
It seems ok

Data seems to well ok also (Quebec city) :-)

Is it because I have a Huawei phone that doesn't support band 4 also known as the dual band frequency 1700/2100 MHz?

Therefore, you phone is not compatible!

For an LTE-compatible phone configured with LTE network preferences:

• Calls: Your device must support HSPA 850 MHz or 1900 MHz frequencies
• Mobile data: Your device must have dual-frequency support for 1700/2100 MHz (also called AWS or band IV)

Your phone can also support other frequencies that allow it to take advantage of the LTE network.

For a phone that only allows 3G or HSPA preferred:

• Calls and / or mobile data: The phone must support the 1700/2100 MHz frequency (also called AWS)
