Largest mobile SMS routing firm discloses five-year-long breach:

Syniverse, a service provider for most telecommunications companies, disclosed that hackers had access to its databases over the past five years and compromised login credentials belonging to hundreds of customers.

Self-described as “the world’s most connected company,” Syniverse provides text messaging routing services to over 300 mobile operators, among them Vodafone, AT&T, T-Mobile, Verizon, America Movil, Telefonica, and China Mobile.

Syniverse is so big that it brags about having as its customers “nearly every mobile communications provider, the largest global banks, the world’s biggest tech companies.”

[...] In a filing on September 27 with the U.S. Securities and Exchange Commission (SEC) spotted by Motherboard journalist Lorenzo Franceschi-Bicchierai, Syniverse disclosed that an unauthorized party accessed on several occasions databases on its network.

When the company became aware of the intrusions in May 2021, an internal investigation began to determine the extent of the hack.

“The results of the investigation revealed that the unauthorized access began in May 2016,” the company reveals in the SEC filing.

For five years, hackers maintained access to Syniverse internal databases and compromised the login data for the Electronic Data Transfer (EDT) environment belonging to about 235 customers.

“All EDT customers have been notified and have had their credentials reset or inactivated, even if their credentials were not impacted by the incident. All customers whose credentials were impacted have been notified of that circumstance” - Syniverse

    My g/f and I send *international* SMSes that arrive within seconds. I know this, because we have phone contracts in different countries, even if we're in the same place. At least one of them has to do an international lookup to find where the other is (smartness can mean that one way can work without it, but not both ways). If yours are taking minutes, get a better provider.

    It may not be the provider's fault, at least not directly. A lot of the delays come from inter-carrier message gateways. You may get lucky that the routing to you does not cross a congested gateway. Of course, you may be left waiting because the person sending an SMS is stuck behind a gateway that's slow to send. There's nothing you can do about it because the real problem is on the other side.

    Back when I was doing cellular tech support we would frequently see delays from one carrier to our customers. An SMS could get delayed by an hour or two, sometimes eight or more hours if it was an MMS. All we could do was tell customers to wait at least 24 hours and ask the sender to send it again if it still didn't come through. Things are way better these days, but delays are still pretty common, even if they're significantly shorter.
