This company is the preferred choice of scammers everywhere. Countless victims have sent money to fraudsters who happily dial Americans from foreign call centers with tempting offers. This company and its evil directors allegedly have single-handedly facilitated nearly 60% of scam calls in the US. They claim to just provide wholesale services and can’t be held responsible for their customers’ conduct. In reality, they hide behind a shadowy catalog of LLCs and shell companies. Research suggests they actually have a major stake in these so-called “customer providers.” And even if they didn’t, knowingly allowing companies that do business with scammers makes them liable. So far, their cunning strategy has allowed them to blame others and sheltered them from any enforcement. It’s a shame our gutless, feckless FCC and FTC have been unable to stop this predatory behavior, jail the executives, and disgorge them of their illicitly gained profits. Shame!

I am extremely disappointed with the service provided by Sinch. Their response times are abysmal, often taking 4-5 months to address any issues. This kind of delay is unacceptable for any serious company. Not only have I lost money due to their inefficiency, but their lack of timely resolutions has been incredibly frustrating. Their customer service is virtually non-existent, and it feels like they don't care about their customers' concerns at all. I would strongly advise against using Sinch for any business needs. Save yourself the trouble and look for a more reliable service provider. I will be sharing my negative experience across all possible platforms to warn others. Sinch has earned the worst review I could possibly give. Maybe this review won't matter to them, but it will certainly matter to potential customers.

You check all the information you can find about their services and all looks good, this one is useable. When the time comes to upgrade the account you get denied without explanation. After sending tickets to their support they simply reply with “there is a risk associated with the details” and you get shut down. “Each piece of information is then vetted and any which do not meet the standards will be declined”. No clarification on what this information is either. Wasted weeks on trying to use their solution to send text messages over pc. Don’t waste your time or resources on this company, take your business elsewhere. And I am not the only one with this experience

We needed to interface our software to Sinch SMS for a customer. We encountered several bugs and configuration problems with Sinch's API. Sinch's Customer Service took two weeks to get back to our developers and only after we chased four times. It turns out Sinch does not support sending to UK numbers at all in development mode. This blocked development and caused us to advise our customer to switch SMS provider. The lack of UK support is really poor given that BT (British Telecom) subcontracts their services for UK customers.

SINCH IS A SCAMMERS-SPAMMERS, FRAUDSTER SERVICE PROVIDED AND EVEN IF YOU TRY TO REPORT THE CRIMINALS THEY SUPPORT TO THEM IT IS IMPOSSIBLE. BECAUSE THEIR FORM HAS A GLITCH. IT IS NOT IN THEIR BEST INTEREST TO LOSE THEIR CRIMINALS PAYING CLIENTS.

AVOID !! fraudulently took money from me, after providing evidence back and forth of ignorant emails from themselves because they won’t admit what they’ve done or meet me face to face they’re closing the case. I requested numerous times their complaints procedure and what ombudsman etc they’re under to complain to be completely ignored of the answer numerous times. They’re thieving liars and absolutely fraudulent so AVOID!!

shockingly bad, i tried to upgrade my account by depositing £10 they first ignored me for a week, i also asked their customer service if they provide actually voice api to make live calls with multiple times an they ignored my question and said i failed security, even though i have a limited company and website i provided them everything, i think this company are just chancers they cant provide so they don't tell you and simply give you a vague response that you didn't pass security after giving all your information, after a couple of weeks wouldnt trust i think they make most of their money of data harvesting, read the rest of the reviews, rude customer service.

As a veteran of some 20 years in SMS, I can tell you Sinch have given us more downtime in 6 months than we've had in aggregate over 20 years from other providers combined. Very poor customer service. Have suffered a lot of downtime as we were migrated from previous SAP platform. They take weeks to do anything including resolve a security policy breach at their end. As a customer I have no importance, feel completely under valued and am left with no way to impact their chronic service on my customers and business. They've grown massively through acquisitions over the last 3 years and are clearly unable to cope. Look elsewhere unless you want a lot of hassle.
