Managing multiple online identities for work taught me one thing fast: your IP, your phone number, and your SIM are three separate attack surfaces and most people only think about one of them.

Here's what worked for me:

1. Mobile proxies over residential and datacenter every time. Residential success rates dropped hard, the big pools are burned and platforms have the ASN ranges flagged. Mobile carrier IPs are the hardest to separate from normal traffic because that's what they are. VPNs are fine for privacy but poor for platform trust, most ranges are already blocked.
2. Stop using your real number for verification. Every time you hand over your real number for a 2FA or account verification, you're creating a permanent link between that account and your identity. Non-VoIP carrier numbers fix this cleanly, virtual/VoIP numbers get rejected on anything serious.
3. eSIM for secondary connectivity and travel. Physical SIMs are tied to your identity at the carrier level (most countries require ID for activation now). eSIMs from a privacy-focused provider give you a clear layer of separation, especially useful when moving between countries.
4. Keep everything under one platform. Switching between three different providers for proxies, SMS and eSIM is where most people leak. Inconsistent setups, overlapping accounts, payment trails. I moved everything to Voidmob and the operational overhead dropped significantly.
5. Pay with crypto where possible. A privacy stack paid for with a card tied to your name is not a privacy stack.

The biggest mistake people make is treating these as separate problems. They're not, they're one problem with three surfaces.
