There are currently three mobile providers in Egypt, I was using my MTC cell phone from Kuwait. There was one issue I was having and I kept switching between the three cell phone providers but it still didn’t solve my problem. For some reason I couldn’t send text messages, it just kept getting rejected I wasn’t sure why.
Providers:
Previously if you buy a temporary line it becomes inactive after 2 months of no use even if it has credit on it, but Etisalat has changed that and you can buy a line and keep it permanently yours for just 25 Egyptian Pounds. Currently the best service providers is Etisalat then Vodaphone, and Mobinil is currently the worst in service strength in Egypt.
