# Mobile Voice (VoLTE) Now Available in the US

### 9, Nov 2026

VoLTE calling is now live on Telnyx [mobile numbers](https://telnyx.com/products/phone-numbers) in the United States. Mobile Voice is in beta while we monitor performance, with worldwide availability to be announced in the coming weeks.

### What's new

* **VoLTE calling:** Place and receive calls over LTE on any US mobile number with [Mobile Voice](https://telnyx.com/products/mobile-voice) enabled.
* **Beta status:** Provided on a best-effort basis. No SLA applies during beta; the SLA will be defined at general availability.
* **Portal and API control:** Enable or disable calls on a single SIM or in bulk across a SIM group. SIMs can be attached to a Mobile Voice Connection via connection\_id.
* **Carrier validation:** Tested on AT&T, T-Mobile, and Verizon across iPhone 14, 15, and 16; Samsung Galaxy S23, S24, and S26; and Google Pixel devices, including Pixel 6a and 9 Pro XL. Physical SIM and [eSIM](https://telnyx.com/products/iot-sim-card) are both supported.
* **Known limitation (iPhone, USC IMSI):** While attached to USC IMSI (IMSI5), iPhones cannot place outbound calls. Set IMSI1 as the default IMSI in the US to mitigate. Android devices are unaffected, and an Apple carrier-bundle update is in progress.
* **Pricing:** $5 per month per SIM with no platform fee. Calling is pay as you go, at carrier fee plus [SIP trunking](https://telnyx.com/products/sip-trunks) rates.

### Why it matters

Most IoT deployments run on data-only SIMs, so any device that needs to place a call, from elevator lines to SOS buttons, has meant a second vendor or a legacy carrier contract. Mobile Voice removes that dependency: one SIM, one API, one network for data and voice. Calling rides the same carrier infrastructure as your [SIP trunking](https://telnyx.com/products/sip-trunks) and messaging, so it behaves like the rest of your communications stack instead of a bolt-on.

### Example use cases

* Elevator and intercom lines where voice availability is a requirement, not an add-on.
* Fleet and asset trackers with a one-touch SOS button for voice escalation.
* Consumer and industrial devices that need to place calls, provisioned over the API at fleet scale.

### Getting started

1. In Mission Control, go to **Mobile Numbers** and select the number you want to enable.
2. Open the **Voice** tab and select "Enable calls on mobile number".
3. For fleet-wide enablement, use the SIM Card Actions API:

curl -X POST https://api.telnyx.com/v2/sim_cards/{id}/actions/enable_voice \
  -H "Authorization: Bearer YOUR_TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"connection_id": "your-mobile-voice-connection-id"}'
