Service for one of Israel's largest cellphone providers has been disrupted.
In a message on its website, Pelephone said the service went down Sunday evening and that it was investigating the malfunction.
It was not clear what caused the disruption, although Israeli media speculated it could be anything from a technical issue to a cyber attack.
Users complained that they were unable to place or receive calls. The company says data services were not affected.
In 2010, another major Israeli cellphone service provider went down for several hours. The cause of that malfunction was never resolved.
