+Verizon and AT&T have indicated that customers who follow Telit guidelines, implement the module similarly to Telit PTCRB-tested configuration, and use the same antenna should generally be able to leverage Telit certifications. However, both carriers reserve the right to require spot OTA testing.
+
+If a customer uses an antenna with a cable of 20 cm or longer, the carriers typically do not require OTA testing. Verizon may still request conducted testing to verify transmit power and receive sensitivity.
+
+The carriers have introduced restrictions on LTE-only certifications. AT&T is no longer accepting new Cat 1 or higher LTE-only certifications, including Cat 1 bis. AT&T is accepting devices with 5G and LTE fallback, as well as Cat M1 devices. Verizon will accept Cat 1 and Cat 1 bis certifications through January 2028 but is no longer accepting Cat 4 or higher LTE-only devices. Verizon also accepts Cat M1 devices.
