That sure is a step backwards on their router change, like they managed to get a good deal of some old stock of B311's from somewhere.
It is well worth trying to get the Huawei B535, even if it's a returned router. At least that will let you attach both antenna leads as well as possibly get faster speed if they use 4G+ (multiple bands) in your area.
In the meantime, it's worth trying the SIM in your Huawei B315 to see if it can make a connection. Copy the APN settings as shown in the B311. For the password, try what's in the username field, e.g. if the username is VIVACOM, enter VIVACOM for the password. If it fails to connect, then it's possibly IMEI locked.
