There are multiple models of each of these routers with differing bands and specifications. I’m dealing with the 2 most common models in South Africa.
Huawei B618 is a LTE-A pro router while the Huawei B315 is only an LTE Cat4 router. Huawei B618 is very good, but Huawei B315 is enough for most common use. Make sure the Huawei B618 and B315 are compatible with your network providers. They both work on the RAIN network.
