TBI Telecom Review: What We Verified

SIPNEX ·

TBI Telecom is the trade name of Third Base International Telecom LLC, a Fort Myers, Florida carrier. It sells US DID numbers, toll-free service, voice termination, and SMS/MMS messaging. A free trial is offered; pricing comes only through sales contact. It’s a small shop with a thin public footprint. That makes it worth reviewing on verified facts, not vibes. It also needs to be told apart from the better-known company that shares its initials.

SIPNEX is an FCC-licensed carrier chasing the same wholesale voice business, so our bias is on the table. Every fact below was checked against the carrier’s own sites, tbitelecom.io and tbitelecom.com, in August 2026.

First: which TBI is this?

Search results overload these initials. This review covers Third Base International Telecom LLC — the Florida carrier at tbitelecom.io and tbitelecom.com. It is not Telecom Brokerage Inc., the Chicago master agent many “TBI telecom” searches actually mean. That firm is a technology solutions brokerage later associated with AppDirect. Researching the brokerage? You’re on the wrong page. Vetting the carrier? Read on.

What we verified

  • Identity and location: the brand is a registered trademark of Third Base International Telecom LLC, headquartered at 3949 Evans Ave, Suite 301B, Fort Myers, Florida. Both domains state this identically.
  • Services: US DID phone numbers, toll-free, voice termination, and SMS/MMS — a classic small-wholesaler portfolio.
  • Infrastructure claims: three Points of Presence (its site also calls them data centers) — Los Angeles, Dallas, Miami — and an advertised “99.999999%” uptime.

The sales posture is contact-driven. A free trial is offered, but no pricing is published on either domain. Support is business-hours with a 24-hour claim. Both sites were live and current at review time — active forms, current copyright, not parked.

The claim worth a raised eyebrow

Eight nines. A 99.999999% uptime pledge implies about a third of a second of total downtime per year. That is beyond what major cloud platforms publicly commit to. We can’t disprove it, and we won’t pretend to. But treat any extraordinary uptime claim the same way — from any vendor, us included. Ask for the SLA in writing, the measurement method, and the remedy when it’s missed. The answer tells you more than the number itself.

How to vet a small carrier — TBI or anyone

Small carriers can be great buys: hungrier support, flexible deals, direct access to engineers. The diligence list is the same every time. It’s the one we’d hand you for vetting SIPNEX too — our questions to ask a SIP trunk provider guide runs the full set. The essentials:

  1. Regulatory standing. FCC filings, Robocall Mitigation Database registration, and — for toll-free — RespOrg status. Verifiable in public databases, not just on the vendor’s site.
  2. STIR/SHAKEN posture. Whose certificate signs your calls, and at what attestation level? A reseller that signs through an upstream adds links to your trust chain. A carrier that signs under its own SP certificate keeps it short.

Then the commercial two:

  1. Pricing transparency. Quote-only pricing isn’t a deal-breaker, but it shifts work to you. Get the full rate structure — increments, surcharges, dips — in writing, per our pricing comparison method.
  2. Trial with your real traffic. A free trial (TBI offers one) only tells you something if you run production-shaped traffic through it. Measure ASR and audio quality, not a five-call smoke test.

Verdict

Third Base International is a legitimate, live, small wholesale carrier. It has a standard product set, an unpublished rate card, and one marketing claim we’d make it defend. Neither a red flag nor a proven contender. It earns a spot on your quote list only after the diligence above. Run its numbers against carriers that publish theirs — like our published rate card.

Frequently asked questions

Who is TBI Telecom?

It is the registered trademark of Third Base International Telecom LLC, a wholesale telecom provider headquartered in Fort Myers, Florida. The company runs both tbitelecom.io and tbitelecom.com. It sells US DID numbers, toll-free service, voice termination, and SMS/MMS messaging, advertises three data centers (Los Angeles, Dallas, Miami), and offers a free trial with sales-contact pricing.

Is Third Base International the same as Telecom Brokerage Inc?

No. Third Base International Telecom LLC of Fort Myers, Florida is a wholesale voice and messaging carrier. Telecom Brokerage Inc. is an entirely different business — a Chicago-area technology brokerage and master agent later associated with AppDirect. The shared initials cause constant search confusion. Check which entity a review, complaint, or listing refers to before drawing conclusions about either.

What services does Third Base International offer?

Per its own sites: US DID phone numbers, toll-free services, voice termination, and SMS/MMS messaging — the standard small-wholesaler stack for dialers, PBXs, and resellers. Claimed data centers sit in Los Angeles, Dallas, and Miami. It is a carrier-services portfolio, not a UCaaS or contact-center software product. You bring the phone system; TBI supplies numbers and carriage.

Does Third Base International publish its pricing?

No — neither tbitelecom.io nor tbitelecom.com publishes rates. Both route buyers to sales contact, with a free trial available. That is common among small wholesalers, but it shifts the diligence burden to the buyer. Request the complete rate structure in writing, including billing increments and surcharges. Then convert quotes to effective cost per connected minute before comparing against carriers with published rate cards.
