Unlimited SIMs
As long as you’re in the UK, yes—tether as much as you want.
In the EU, tethering comes out of your monthly allowance, which is 25GB per month.
Outside of the UK & Europe, you’ll need one of our roaming add-ons. We want to keep the network fair for everyone, so fair use policies apply to all tethering.
Ever notice your internet speed slowing down for no reason at all—especially when everyone gets home in the evenings?
It’s because most mobile networks make you share bandwidth with other users on the network. The more people streaming music, sharing cat videos, and video calling their friends, the slower your connection. Kind of like a traffic jam.
But the way we route traffic over our network is different to (better than) how other operators do it.
When you use one of our unlimited SIMs, you don’t share your bandwidth with anyone. No traffic jams—you have the roads all to yourself. (If you’re fluent in mobile tech jargon, you can check out our O2 and Vodafone APNs that make this possible.)
Other operators only do this for their corporate customers. Rude, right?
Yep! Go wild.
We do, however, want to make sure the network is fair for everyone. So if your usage reaches 650 GB and breaches our Fair Use policy, we’ll quickly check in with you to make sure you are aware Fair Use Policy. We can stop services if you use more than 650 GB in a consecutive period. “Unlimited” is unlimited data for a single device/user, with periodic tethering, not for use by multiple or non-consumer users.
To monitor your usage, please log in to your Account, or if you need Account access, contact info@onecallsim.com.
No credit check
Not a problem! You can still get your unlimited SIM. No nonsense from us—just your SIM and your service.
You’ll need to use an old phone or buy a new one fresh. But once you do, we’ve got your no credit check, unlimited SIM covered.
Our subscriptions are SIM-only and paid upfront. So there’s no need for the hassle of a credit check.
