I have a Lumia 635 which connects at LTE everywhere except where I work. Outside the building I get LTE, inside I get E (EGPRS) which connects at 236.8 kbps. I have a Samsung cell on a different provider that connects at LTE in the building with download speed of 35 mbs. Is this problem due to the frequencies Fido uses or is something wrong with the phone. I do not get 3g, 2g or H or H+ connections. It is either LTE or E.
