I got a call from someone saying they were from O2, saying I could get 40% off if I told them how I found their service. Then they started asking for my email and some other personal stuff which felt a bit dodgy to me.

Just got a call from this number, and I think it's a scam. A woman said she was ringing from 3 Network offering a 40% discount for a whole year. I asked if she was really with 3, and she said yes, but the number looked dodgy to me. Then she asked if she should activate the deal. I told her no since we hadn't agreed to anything. She ended the call straight away, so I’ve gone ahead and blocked the number now.

total rip off - dont ever answer if these call you. they want to break into your phone and steal info. just throw them a made-up postcode and they’ll try to use it as some kinda ‘security check’. really not on, stay clear.

I got a call from someone claiming to be with 3, and they said because I’m a loyal customer, they’d give me a 40% cut on my bill. Sounds good, but honestly, I’m not convinced it’s some kinda scam or anything.

Didn’t think I’d get a call from London, so I’m guessing it’s probably some kind of scam.

I got a call from someone trying to sell me a cheaper phone contract, but they never really said which company they were from. It all sounded a bit dodgy to me. Feels like it could’ve been a scam, so watch out!

Twice today I got calls from this number but I never picked up. There's no one I know who stays in London, so I'm pretty sure it's just some scam.

They’ve been ringing me nonstop for days now, just got another call today, 7th April. I didn’t answer since I always reckon 020 numbers are dodgy and usually from cold callers trying to mess with me.

I got a call from 3 claiming they wanted to offer me a discount. The woman on the phone said she’d be sending me both an email and a text, but I reckon it was a total scam. Definitely be on your guard!

I received a call from the same number "020 3504 6435" today. I accepted the call but didn't speak. An Indian male started speaking and i replied. Couldn't hardly understand him but i picked up that he said i was a loyal customer of the 3 Network. The rest was just gibberish to me but i could hear a females voice nearby. Told him if i have problems that i contact the 3 shop in town etc.

At first, they claimed to be with Three, but then switched to saying they were from EE, which is the provider I actually use. Their call was about giving me a deal to lower my EE plan costs. I pointed out how their number popped up clearly on my phone and told them bluntly that they’re making it harder for people like me to keep hold of our money. The lady said my voice sounded choppy. I replied with, “Your mates nearby must be real chuffed about what you’re doing to folks.” She snapped back with, “Don’t need your opinion, cheers,” and then just ended the call.

They told me my sim card was outdated and said they’d replace it. I asked why they didn’t just post a new one instead. It honestly gave me vibes of a scam right away.

I missed two calls back to back since I was busy at work, then when I tried calling back, all I got was some automated voice telling me to hold on while they try to put me through.

They phoned me, it rang a few times then cut off without leaving a message. I rang them back and someone with an Asian accent said it was "Smart Wide Solutions" and asked me to wait on the line. After that, the phone just kept ringing with nobody answering. After about a minute I gave up trying. Ended up blocking the number - totally pointless.

Got a call from someone saying they were with Three, offering a discount on my plan. I don’t even manage my Three account myself and have never had any official calls from them. Seems dodgy, probably a scam.

Got a call from this number at about 10:40 on 3rd March 2026. Didn’t recognise it so I sent it straight to voicemail. They didn’t leave any message though. After looking up the number, it seemed dodgy with reports of suspicious activity, so I’ve gone ahead and blocked it and removed it from my phone.

I got a missed call and when I checked the voicemail, all I could hear was heavy breathing. Quite weird if you ask me!
