Connectivity decisions in Singapore hinge on licensing, route diversity, and contractual SLAs far more than headline speeds. Use this checklist to separate a resilient carrier partner from a thin reseller before you commit to a 24-36 month term.
How to evaluate a telecommunications / connectivity provider in Singapore
- Confirm the IMDA licence class behind the service: an FBO owns fibre, spectrum, and exchanges, while an SBO resells that capacity — for low-latency, mission-critical links, ask which underlying carrier actually delivers the circuit.
- Pin down the SLA in writing — committed uptime, latency, jitter, packet loss, and a named MTTR with a credit schedule — and reject any "best effort" language for business-grade lines.
- Ask for route and carrier diversity: verify that primary and backup paths use physically separate ducts and ideally separate carriers, not two lanes in the same conduit.
- Lock down installation lead times and require a site survey upfront — fibre installs can run 4-12 weeks — and negotiate 30-day dual-running of old and new services to avoid a hard-cutover outage.
- Read the termination and exit terms before signing: early-termination charges, notice periods, IMDA-mandated number portability for any fixed-line or mobile numbers, and who owns the on-site equipment at the end.
- Map data sovereignty for voice: ask where call recordings and CDR/metadata are stored and processed, and require PDPA-compliant cross-border clauses if any of it leaves Singapore.

Questions to ask
- What committed uptime, latency, jitter, packet loss, and MTTR are in the SLA, and what credits apply when you miss them?
- Are the primary and backup routes physically diverse, and which underlying FBO carries each path?
- What are the full early-termination charges, notice period, and number-porting process if we leave?
- What is the realistic installation lead time after a site survey, and can you guarantee dual-running during cutover?
