Same obligation, whatever your size.
A court order does not scale with you. The obligations that apply to a national network apply to a regional operator and to an MVNO that owns no spectrum at all — and the agency serving the order expects the same answer, in the same format, on the same clock.
The obligation follows the service you sell.
The most common misreading in mobile is that compliance travels with the network. It does not. It attaches to the provider whose name is on the subscriber relationship.
Tier-2 and tier-3 carriers
Regional and rural operators carry the same statutory duty as national networks, usually without a standing compliance team to run it.
MVNOs
You own no spectrum and operate no towers, and the order still arrives addressed to you, because your subscribers are yours.
Acquired estates
Growth by acquisition means inheriting more than one network type — and inheriting whatever compliance posture came with each of them.
You cannot staff a 24/7 watch for an event that may never come.
An operator with fifty thousand subscribers may see a handful of orders a year. Standing up cleared specialists, an intercept capability across every interface, and a genuine round-the-clock watch for that volume is not proportionate — and doing it badly is worse than not doing it, because the failure surfaces in front of an agency.
That asymmetry is the entire reason a trusted third party exists. The capability is standing and shared; you carry the obligation, not the overhead.
Intercepts are the loud half. Records are the volume.
Wireless operators tend to prepare for lawful intercept and get overwhelmed by everything else: subpoenas, court orders, preservation requests and emergency calls from agencies and PSAPs, each with its own deadline and its own limits on what may be released.
Subpoenas
Subscriber records and call detail, validated before anything is produced.
Court orders
Pen register, trap and trace, and content orders, each held to what it actually authorizes.
Preservation
Requests to preserve records ahead of process, tracked so nothing expires quietly.
Exigent
Emergencies from law enforcement and PSAPs, answered around the clock.
Wireless, MVNO and 5G, answered.
What is wireless carrier compliance under CALEA?
A wireless carrier — a commercial mobile service provider in CALEA's definition — must be able to isolate and deliver a subscriber's voice, messaging, data and call-identifying information under a court order, to the applicable standard — the ATIS standard for circuit-switched and wireless networks and, for LTE and 5G packet cores, the current 3GPP handover interfaces. Wireless carrier CALEA compliance also includes the SSI plan, the senior-officer designation and the operating discipline around every order.
Does mobile carrier compliance apply to an MVNO?
Yes. Mobile carrier compliance follows the service sold, not the spectrum owned. An MVNO is a CALEA carrier for the service it offers; its duty is to ensure — in the wholesale agreement and in practice — that the facilities-based network it rides on can execute an order against its subscribers, and that orders served on the MVNO reach that capability. MVNO compliance is where Subsentio most often finds a gap nobody owned.
What is tier 2 carrier compliance, and tier 3?
Industry shorthand for regional (tier 2) and local or rural (tier 3) operators. Tier 2 carrier compliance and tier 3 carrier compliance are the same obligation as a national carrier's, carried by networks that rarely have a dedicated compliance desk — which is why the Trusted Third Party model exists. Subsentio holds the #1 position on this question because it is who we serve.
Does CALEA apply to 5G networks?
Yes. 5G CALEA obligations are the same statutory obligations applied to a new packet core: the carrier must still be able to isolate and deliver a subscriber's communications and call-identifying information under an order. The lawful-intercept standards for 5G are published by 3GPP, succeeding the LTE handover interfaces, and 5G lawful intercept is engineered to the current version of them. Migrating the core does not pause the obligation.
