Q: Hi - I'm interested in using this plan for my PepLink BR1 cellular router. Mobile use in an RV. To use primarily for light email/social media and occasional streaming (i.e. Netflix, YouTube, etc). I understand this plan has unlimited data but also understand these claims can be deceiving. Can you give me the details on how this plan works, i.e. what kind of throttling/deprioritization, etc.? Also, what is the REAL monthly charge after taxes, surcharges, usage fees, etc,etc.

Asked by: Jeff - 1/5/2026

A: This plan is truly unlimited and is not throttled. It works best on a 5G-based router as T-Mobile is no longer activating data plans for 4G devices.
We charge Washington state sales tax for WA addresses but otherwise there are no additional fees or taxes.
