This number rang for one second and then called again shortly after. It looks like a nuisance or callback-bait call.
1 Ring call, I'm reporting it as this number has been flagged by others.
Rang for 1 second just after 17.00 and then again 1 minute later. Suspect a spam caller.
Called to say they’re from EE. Cut off immediately.
I didn't answer, but I'm flagging it as the number is clearly still calling people.
Claimed to be EE, dodgy and blocked
Calling saying they’re going to block a SIM card after I sent it to voicemail. Reported as SPAM
Indian guy, crap phoneline, telling me my sim was going to be cancelled. Bullshitters. Scam callers
I did not answer - unknown number to me which I searched online for to check if I should ring back - think it's spam
Called me telling me he was from Vodafone and that my sim was being cancelled. Hung up, I suggest you do the same.
I didn’t answer but wanna report it since they’re still active
Indian? Woman saying she was from Vodafone and my SIM card will expire in 3 days. Told her to prove she was from Vodafone! She then hung up the call. Be warned this is a scam.
Indian called Mary from O2 network apparently sending me a new SIM card tomorrow via DPD I didn't give any info over she hung up after telling me to check my email for a confirmation which is guess is the scam, probably a phishing link email.
Told me her name was Mary from Vodafone and that my sim ending in **7 will be cut off in 2 days. Hung up call lasted 28 seconds! Didn’t wait around to see what they wanted instead of being cut off I’ll take my chances!
