When I asked for an explanation of this, it had to do with a corporate silent-treatment of sorts; because Paltel/Jawwal (the Palestinian telco) was suing Cellcom for licensing infringement and illegal operation, the Cellcom network decided to boycott the Palestinian phone carriers. This caused all sorts of problems for Palestinian society, and the effect was that everyone in Palestinian areas were ditching the local telco and getting Israeli Cellcom cell phones. Jawwal was facing dire times, after their offices were raided by Israeli military and tech imports were prevented because of blanket security concerns.
For folks on the ground, this was just one more manifestation of the intifada/occupation, even the corporations were going at it.
