Global cellular certifications determine if Cradlepoint endpoints are safe to operate on a carrier/operator network. Cradlepoint typically achieves two cellular industry certifications: PTCRB for North America and GCF-CC for the rest of the world. Adhering to these cellular standards allows a Cradlepoint product to work globally.
Not all carriers in a particular country are licensed to uniformly support all of the cellular frequency bands that a particular modem in a Cradlepoint endpoint is capable of using. Customers and partners should ensure their choice of a carrier in a given country meets the use case and operational needs the selected Cradlepoint endpoint can provide. Here’s good reference of carriers by country.
