Perhaps JMP.chat is an option. Does anyone have experience with it?


---

### **1. JMP.chat (XMPP-based)**
- **Features**: Get a real phone number, SMS/MMS support, pay-per-minute calls to landlines/mobiles.
- **Payment**: Bitcoin via BTCPayServer (non-custodial, no KYC).
- **Cost**: $0.03/min for calls, $0.01/SMS + small monthly fee ($1.50).
- **Setup**: Requires XMPP client (e.g., Siskin, Conversations).

---

### **2. Localphone**
- **Features**: Call 200+ countries, no subscription.
- **Payment**: Bitcoin via BitPay (check BitPay’s KYC thresholds; small amounts may bypass).
- **Cost**: Rates start at $0.01/min.

---

### **3. VoIP.ms (SIP Provider)**
- **Features**: Pay-as-you-go SIP trunking for calls/SMS.
- **Payment**: Bitcoin accepted (account creation requires email/name, but minimal verification).
- **Setup**: Use apps like Linphone or Zoiper.

---

### **4. Bitrefill (Indirect Option)**
- **Features**: Buy refills for services like Viber Out, Dingtone, or Lycamobile with Bitcoin.
- **Limitations**: Some services may require phone number verification.

---

### **5. Self-Hosted Asterisk/PBX**
- **Advanced**: Host your own VoIP server (e.g., Asterisk) and pair with a Bitcoin-friendly SIP provider (e.g., Callcentric).

---

### Privacy Tips:
- Use a **VPN** (e.g., Mullvad, accepts Bitcoin) to mask your IP.
- Pair with a **Bitcoin wallet** like Sparrow (CoinJoin support) for transaction privacy.
- For email signups, use **ProtonMail** or **CTemplar** (anonymous accounts via Tor).

### Example Workflow with JMP.chat:
```bash
# 1. Install XMPP client (e.g., Siskin on iOS/Android)
# 2. Sign up at JMP.chat, pay via Bitcoin
# 3. Configure XMPP client with JMP credentials
# 4. Call/SMS directly from the app
```

Avoid services like Skype, Google Voice, or WhatsApp—they require phone numbers or KYC.
