AeriSIM does not provide an eSIM for Macau that includes a phone number or SMS capability. The only plans available from AeriSIM for Macau are data‑only options, so travelers will not receive an assigned local number for traditional voice calls or text messages.
Because of this limitation, users can still communicate via internet‑based services such as WhatsApp, Telegram, or iMessage using the data connection. However, travelers should verify whether these VoIP applications are accessible in Macau, as some destinations may block or restrict specific services.
