Switch on these settings to secure your phone numbers

On Graphene OS:



Don’t use phone numbers, if you have to, use jmp.chat (referral code : BKTK57SA free one month of service) , it’s far better for you to use USA & canada numbers for online services especially if you don’t live here, ask for premium+ numbers for online verifications, they work! Migrate, Migrate, Migrate. Ask support to verify, calling via verification can also work.

Use seperate numbers for banking, spam & gov id

If your banks use SMS for 2fa, try to shift them to email,

WhatsApp e2ee calls are far better than normal calls.

Location & stringrays are easy targets, airplane mode can only help.

If you can’t find a VoIP for your country code, I am making a DB, comment down your country and I maybe able to help.

On Cape:

IMSI rotation without IMEI and EID rotation wouldn’t amount to much.

“Secure core” helps in esim provisioning not being routed through malicious servers.

The plan is very very expensive and you have to use their app. I haven’t tried their service but if I have to guess for IMSI rotation you need to download and apply new esim profiles.

Location isn’t decoupled so you can still be triangulated and stringrays will still work. (Jmp chat protects against this)

Cape claims they don’t use ss7 but if they didn’t they won’t be able to contact a lot of operators, they prob do ss7 filtering but that requires the app and the app needs location permission
