The most common beginner mistake is cheap — it costs exactly one account. The number is from one country, the proxy from another, because that one was cheaper.
How it looks from outside
The account was registered on a number from country A. Its first login came from there too. Then it reaches you and suddenly appears from another part of the world, without ever showing up anywhere in between. To a system watching for account takeovers this is the textbook pattern: a country change with no intermediate steps.
The same root cause produces repeated login codes — see why Telegram keeps asking for a code.
What has to match
Country: mandatory. City: preferable, not critical — people travel. Carrier and address type: where possible. A mobile number with a mobile proxy from the same region gives the smoothest picture.
Time zone is its own story. An account on a Brazilian number that is active strictly from nine to six Moscow time looks like exactly what it is. See quiet hours.
If the geo has already drifted
Do not jerk it back. A sudden return is a second country change in a short window — another signal. If the account works, keep it on its current address permanently; change only as part of a careful move.
Buy new accounts for regions where you already hold proxies. That is cheaper than hunting addresses to fit numbers you already own.
