Typical speeds of 10–80 Mbps
Plenty for maps, streaming, video calls and tethering a laptop. Peaks well above that are common on 5G, and we apply no cap of our own.
Coverage & networks
Three networks, one SIM, no favorites
Most dead spots belong to a carrier, not to a place. FlexiFone gives your device all three national networks so it can pick the one that actually works.
AT
AT&T
5G and LTE, nationwide including Alaska, Hawaii and Puerto Rico.
TM
T-Mobile
5G and LTE, nationwide including Alaska, Hawaii and Puerto Rico.
VZ
Verizon
5G and LTE, nationwide including Alaska, Hawaii and Puerto Rico.
FlexiFone is an independent MVNO. Network names are the trademarks of their owners and appear here only to identify the networks our SIMs can reach. Coverage and speeds are determined by those carriers and are not guaranteed.
Unsteered
What “unsteered” actually means
Plenty of SIMs claim multi-network access. The question is who decides which network you land on — the signal, or a wholesale contract.
| Behavior | Unsteered (FlexiFone) | Steered |
|---|---|---|
| Which network you get | Whichever is strongest where you are | Whichever the provider has a deal with |
| In a dead spot for one carrier | Moves to another network | Stays put and stays offline |
| Choosing a network yourself | Allow or block any of the three | Not usually possible |
Straight answers
What to expect, honestly
A roaming multi-network SIM is a trade. Here is both halves of it, so nothing is a surprise after you buy.
No throttling or de-prioritization by us
Your whole allowance runs at full speed. We don't slow you down at 80% used and we don't meter hotspot traffic separately.
Slightly higher latency than a native SIM
Traffic is roaming domestically, so add a few milliseconds. You'd notice it in competitive gaming, not in a video call.
Carriers prioritize their own subscribers
At a packed stadium on a Saturday, a native postpaid SIM on that carrier will beat a roaming SIM. That's true of every MVNO.
Roaming in 75+ destinations
Take your plan abroad and use up to 25 GB of your allowance outside the US per 30-day period. The current destination list, and which zones are included, are in your account.
