Good questions. Clear answers.

What is the difference between Physical and VoIP numbers?
Physical numbers come from real SIM cards on live mobile carriers — strict platforms like WhatsApp, Google and banks accept them. VoIP numbers are app-based +1 (USA) numbers: much cheaper, held for you alone for up to 90 days, but some strict platforms block them.
Does the VoIP USA number work with WhatsApp or Google?
Not guaranteed — WhatsApp, Google and banking apps often detect and block VoIP numbers. For those, choose Physical. VoIP USA is ideal for social apps, email signups, casual platforms and anything you want a long-term number for.
What happens when my 90-day VoIP number expires?
Near day 90 you can renew in one click and keep the same +1 number, or let it retire. No silent auto-charges — renewal is always your explicit action.
What if a code never arrives?
Physical orders have a reservation window. If it expires without a code, 100% of the price returns to your balance automatically — no support ticket needed.
What payment methods are available?
USDT on BEP20 (BNB Smart Chain), USDT on TRC20 (Tron), and native Litecoin. Every deposit gets a ticket with a unique exact amount, valid 24 hours, credited only after enough confirmations.
Can other people receive codes on my number?
No. A VoIP number is dedicated to one account for its whole rental, and a physical number serves exactly one order — one code, then it retires.
Your code. Your pick.
A for the ones that must work. B for everything else. Services and prices are clear either way.
