The best mobile carrier and/or SIM card provider is the one that works best in your area, therefore we recommend obtaining SIM cards from the carrier with the best signal reception for you.
If you're unsure which carrier is best for you, temporarily test multiple SIM cards from different carriers to find the one with the strongest signal. This approach ensures optimal performance when using your mobile proxies.
For users in the United States using USB modems, please note that a hotspot plan is required for proper functionality.
Carriers We Do Not Recommend:
Verizon (United States): Verizon SIM cards are incompatible with USB Modems. However, they should have no issues with Android phones.
Vodafone (UK) and Telstra (Australia): Users have reported issues with mobile proxies not changing IPs when using these carriers.
