# TMPX > TMPX sells 4G LTE mobile proxies backed by physical SIM infrastructure in the USA, Austria and Germany. Each purchase gets an assigned authenticated endpoint rather than access to a public residential pool. Plans are prepaid for 1, 3, 6 or 12 months in USD, paid by crypto or bank transfer; there is no automatic charge. The European network (Austria & Germany) is self-operated on our own hardware and SIM cards; US lines use premium mobile-carrier infrastructure. Mobile IPs use carrier-grade NAT. A public carrier exit can be shared by ordinary subscribers even when the authenticated proxy endpoint is assigned to one purchase. ## Plans - [All plans & pricing](https://www.tmpx.io/plans): Mobile-proxy, VPN and Multi-SIM plans with prepaid terms. - [24-hour test](https://www.tmpx.io/test): Test the product and country for 24 hours before a monthly plan.
