What this category covers
International spam now arrives in two distinct flavours. The first is Wangiri — a single-ring missed call from a country code you do not recognise (typically +252 Somalia, +211 South Sudan, +675 Papua New Guinea, +247 Ascension Island), designed to bait you into calling back to a premium-rate number that bills your operator at $10 — $25 per minute. The second is voice-broadcast spam from large overseas call centres pushing tax-refund scams, fake Amazon order confirmations, Social Security threats, and Microsoft technical-support pop-ups.
Because international VoIP gateways spoof caller ID at the SIP layer, even apparently local numbers can originate overseas. PhoneLookup aggregates community reports across geographies, so a number ringing your phone for the first time in India may already be flagged by hundreds of victims in the UK, US or Australia.
Red flags
- A single-ring missed call from an unfamiliar country code, especially +252, +211, +675, +247, +88216 or +371.
- A pre-recorded English announcement claiming to be from the IRS, HMRC, Amazon, Apple or Microsoft.
- Aggressive English-accent callers demanding immediate payment of ‘taxes’, ‘parcel duty’ or ‘activation fees’.
- Calls timed for the recipient’s late-night hours — a classic offshore call-centre signature.
What to do
- Never call back an unknown international missed call. If it was important, the caller will message or email.
- Block the country code prefix entirely if you do not have international family or business contacts there.
- Report the number on PhoneLookup so the global community gets earlier warning.
- If you are billed for an accidental callback, dispute the charge with your operator citing TRAI premium-rate disclosure rules (or the equivalent in your jurisdiction).
Real-world examples
+252 Somalia Wangiri
Victim sees one missed call from +252 9X XXX XXXX overnight, calls back assuming it was a colleague abroad, and is billed ₹1,400 by their operator for a 90-second connection to a premium-rate trunk.
Microsoft tech support
Pre-recorded voice in English warns the recipient that their Windows computer has been hacked and offers to transfer the call to a Microsoft engineer — who then asks them to install AnyDesk and pay a “security license”.

Frequently asked questions
Why do I keep getting missed calls from +252 / +211 / +675?
Those country prefixes route to international premium-rate trunks that the originator earns a share of when you call back. The cost of placing the missed call is near zero, the cost of your callback can be very high.
Can I block all international calls?
Most carriers allow you to block outgoing international calls via the dialer settings or by calling support. Inbound international blocking is rarer; use the phone’s built-in spam filter or a third-party blocking app.
