Deciding Factors: Sinch Vs. Market Average

Performance of Sinch Across Market Features

Sinch Likes & Dislikes

Voice calling support is among the fastest latency and most reliable HD calling is great - when available single-interface SMS/MMS gateway API is decent

Breadth of channels makes it possible to perform one integration and serve the needs of many markets and clients.

The ease of implementation using the vendor's APIs is what we have liked most about their product and service. Adding new services is always easy.

NOC team support is very poor. Slow to respond, very little feedback, often unaware or unwilling to believe there is a major outage

Sinch feels like a large, disconnected company which makes it difficult to get service and talk to subject matter experts when needed. Account reps often deflect or decline requests for features. Multiple kickoff calls for new features have displayed a lack of prior communication or preparation. Pricing negotiations are prolonged and challenging.

(1) UI does not refresh detailed information quickly enough - there are delays that can prevent detailed information from being available for hours sometimes. (2) Technical support is not in North America, resulting in a slight delay at times.

The service provider's service was easy to implement, and has been easy to use as well. Their customer support team has been responsive and helpful with all aspects of implementation and production. We have used them for 3 years now and have always enjoyed the experience.

Overall the experience has been positive, but I find it difficult that so many things are labeled as "Sinch" when indeed there are multiple platforms (inteliquent vs. voyant), and having separate resources per platform/product.

Sinch is a very good service provider that I would highly recommend.

Oct 24, 2025

My company has been using products from Sinch for many years. So far, we have received very good support from Sinch whenever there are any issues, upgrades or regulatory changes needed for any of the APAC countries. The account manager is very knowledgeable and has been around long enough to share any information on past history when required.
