WhatsApp messaging can work in Egypt over Wi-Fi or mobile data, but voice and video calling availability may be affected by local network restrictions.
Adding a travel eSIM normally does not change the number registered to the WhatsApp account.
NoveSIM provides data only and does not include an Egyptian number, traditional calls or SMS.
Quick answer: Expect WhatsApp messages and media to use your internet connection, but do not rely exclusively on WhatsApp calling. Keep your existing account number and prepare another way to contact accommodation or emergency services.
