Protect your Ada-beware of SIM card SWAPS

Tuesday the 17th I went to Labyrinth theater company and Atlantic theater company co-production of “Halway bitches go straight to heaven.” I’ve seen the show before and the cast has done such a wonderful job that I wanted to watch it again to study their performances closely.

During the intermission, around 8pm my phone stopped working. I couldn’t get service, so at first I paid it no mind. I watched the show, then headed home. I went from Manhattan to Brooklyn but still there was service. I reset the network setting on my phone, took out the SIM card and still no service.

I found the timing of this extremely suspicious with Cardano incentivized test net starting. I decided not to delegate my “stake” just yet, until I figure out what’s going on here. I shutdown my computer, did not touch my :ada: at all. The next morning I called T-Mobile to find out what’s going on. According to their representative I or someone authorized on the account had walked into the T-mobile store the night before around 6:30pm and changed the SIM card on my number. I assured them that I hadn’t done it and there was no one else authorized on my account. I suggested that perhaps it was a hacker or a bad actor. The representative was genuinely surprised and said “we take fraud very seriously and I can see on here the employee ID of the person who made this change, but I don’t think anyone would be dumb enough to do it. I’ve only seen it happen once in four years I’ve worked here and it was a crazy jealous girlfriend that was a T-mobile employee.”
I asked her which T-mobile store was the SIM card swap made and although she couldn’t pinpoint the exact location from her screen, she could tell that it was from NY.
She (the T-mobile representative) was very helpful and submitted a fraud report on my behalf and suggested that I go into the nearest T-mobile store and do a sim card swap myself to stop the bad actor from accessing my phone number. She even happily reimbursed me for the cost of the new SIM card. The fraud report would take two days.
During all this my email account password stopped working as well. All my attempts to reset it did not work; the second verification, the alternate email address and obviously the phone verification. Just now I ran into this article;

I’m suspecting that is what’s happening here. I’m cautioning the community members that if your phone goes off line and you can’t get service all of the sudden call your service provider immediately, submit a fraud report, do a SIM card swap and change all your passwords. To prevent yourself from becoming a target of scams do not publicly share information about your :ada: holdings.


Jesus Henry Christ!

Luckily I only use google authentication for all my crypto needs.

hot damn Sean… that’s unreal. I’ve had my CC# stolen/abused multiple times over the years… but this kind of (SIM) theft is quite novel. Glad you reacted on time and hopefully change your passwords everywhere and maybe get some 2FA Auth going, as painful as it can be, it helps deter this…

After reading this I was horrified when my bank told me they would change from ITAN to SMS-TAN. There’s just a huge security problem in the telecommunication companies.

Thank you @MartinMKD. I have 2FA Auth, I couldn’t change my email password using that either. Once I got my number back using a new SIM card I was able to take control of my email account back.

good that nothing else happened. Sean, you are now a recognizable person, so stay vigilant double


I don’t know about being recognizable :sweat_smile: @basia, but I’ll definitely stay vigilant! Please stay on your guard as well!
