Calling Eritrea Successfully: Common Mistakes & Best Practices
Most failed calls to Eritrea come from one of four mistakes, not from network problems. The most common is mishandling the leading 0: domestically, Eritrea numbers are written with 0 at the front (e.g. 07123456), but that 0 is the domestic trunk prefix and must be removed when calling from outside Eritrea. Dial +291 followed directly by the local number without the 0.
The second is misreading the area code on landline numbers — Eritrea numbers may have variable formatting depending on the carrier and city, so confirm the area code with the recipient before dialing. The third is dialing during off-hours — Eritrea uses local business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.
For scam-call awareness: +291 is the legitimate Eritrea country code, and most unsolicited calls from +291 numbers are legitimate calls from Eritrea-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +291 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
