Palestine is a notoriously difficult destination to deliver SMS due to heavy filtering by carriers. In many cases, even legitimate application to person (A2P) traffic is blocked and so cheap signalling/roaming links do not deliver well particularly for high value content such as password delivery or alerts. In order to get around this filtering, Nexmo uses high quality routes to all networks in Palestine.
