Connection can be revoked.
Roaming permissions are granted at the carrier's discretion. They can be throttled or pulled without warning if traffic patterns trigger a permanent-roamer policy.
Every NuvoLinQ device runs on a permanent, authorized contract with a Tier 1 carrier, not a borrowed roaming permission that can be revoked. Five direct agreements across North America, 175+ countries through the same direct-contract model worldwide.
01the roaming problem
Most multi-network IoT SIMs don't hold a contract with the carrier their device is using. They ride on a roaming agreement, which carriers can throttle, revoke, or refuse outright. For payments and other mission-critical devices, that's a risk the business can't carry.
Roaming permissions are granted at the carrier's discretion. They can be throttled or pulled without warning if traffic patterns trigger a permanent-roamer policy.
Roaming traffic is hauled back through the home network's core before reaching the local carrier — adding hops, geography, and round-trip time on every transaction.
When the active roaming partner has an outage, the SIM can't simply jump to another carrier, it has to renegotiate via the home network, which the outage may itself be blocking.
Regulators in some jurisdictions don't recognize a roaming SIM as a domestic connection, creating audit findings around data residency, lawful intercept, and operator-of-record obligations.
02what direct tier 1 means
The fastest way to understand the difference is to look at who NuvoLinQ holds the agreement with, and what authority that agreement carries. A roaming SIM borrows permission from a host carrier. A direct-Tier-1 SIM is the carrier's own subscriber.
Your device is registered with a small home network somewhere overseas. Every other carrier lets your packets through only because that home network has a roaming deal with them.
NuvoLinQ signs the contract with each carrier directly. Your device is treated as that carrier's own subscriber — same as a phone bought in their store.
03The five North American carriers
In North America, NuvoLinQ holds direct agreements with every major carrier our customers ask us about. Each one is a signed, permanent contract, not a partner-of-a-partner relationship.
Five direct-Tier-1 agreements covering the population centers your fleet actually operates in. Each device picks the strongest available carrier from this set in real time.
04why pos is different
A card-present transaction is a tightly-timed conversation between terminal, processor, and bank. Every extra hop is a chance for the host to time out. Every revoked roaming permission is a transaction that doesn't happen, and a customer who walks out.
Card-present transactions time out in seconds. Roaming SIMs add hops by design, your packets are pulled through a foreign home network before reaching the carrier next door. NuvoLinQ devices go straight to the local carrier.
Your packets reach a carrier NuvoLinQ has a signed contract with — no detour through a foreign home network.
Every fallback carrier already sees the device as one of its own subscribers — no renegotiation.
05Automatic carrier switching
Because every carrier in the set is a direct contract, the SIM doesn't need to renegotiate through a home network to switch. The modem just picks the next-best signal and the session continues on the new carrier.
Because every carrier in the set is a signed contract — not a roaming permission — the device can move between them on its own, without anyone touching it.
It's always watching. The SIM listens to every carrier in your area, even while one is in use.
It picks the strongest one. When the current carrier weakens, the device hops to the next-best signal on its own.
It tells you what happened. Every switch shows up in LinQView: which carrier, when, and why.
06Beyond North America
The five North American carriers are the headline, but the same principle scales. NuvoLinQ extends globally through a partner network where every link is a contractual agreement, not a chain of roaming permissions.
Where NuvoLinQ doesn't hold the carrier contract directly, we hold a direct partner contract with the operator that does. The chain is short, named, and contractual — the same standard we apply at home.
The rule we don't break: if we can't tell you which contract authorizes traffic on a given network, we don't connect to it.
Every connection traces to a signed agreement — domestic or partner. No grey-route relationships, no permanent-roamer workarounds.
