Questions About Creating a TikTok Farm Using Android Phones for Advertising

Hello everyone,

I am planning to create a TikTok farm and would like to clarify a few doubts before getting started. The idea is to purchase 10 Android phones to run ads directly through the app using the "Promote" button, targeting my own country (Europe).

My questions are as follows:

1. Use of SIM Card or Proxy: To operate these accounts efficiently and avoid blocking issues, should I use a SIM card for each phone or would it be better to use proxies? What are the advantages and disadvantages of each approach?
2. Number of Accounts per IP: How many TikTok accounts is it safe to create and manage per IP without risking being blocked or flagged? Is there a specific recommendation for this?
3. Card Contingency: How can I handle the issue of card contingency in a cost-effective manner? Are there any strategies or services you recommend for managing multiple payment cards for ads without incurring high costs?

Thank you in advance for your help and guidance!

Best regards,
