Situation 1: 3G/4G modem/Region/ISP is not listed in the compatibility list of our router.
We recommend our users to check the 3G/3.75G USB Modem Compatibility List before purchasing our 3G
router. This list contains the tested modems with corresponded information such as region/ISP. If your country is not
in the list, please take “Other Location” option for reference only.
Please note, due to the firmware upgrading or various parameters changed by some 3G ISPs, there are some 3G
modems in the "Other Location" list that may NOT be compatible with our router. So please be careful with the “Other
Location” list.
If you have a 3G modem out of the region’s compatibility list, we recommend you to test your 3G modem with
our router before purchasing, and we do really appreciate receiving your feedback to TP-Link Support as it is really
valuable information for other customers.
