Voice over LTE (VoLTE) is a voice calling service that allows subscribers to make and receive voice calls over BTC’s 4G/LTE network. VoLTE offers enhanced call quality (HD Voice), faster call setup, and the ability to use voice and mobile data services simultaneously.

By using the BTC VoLTE service, the subscriber agrees to the following Terms and Conditions.

1. Service Description & Eligibility

• VoLTE is provided as an enhancement to traditional voice calls over 4G LTE networks (HD voice, faster call setup, simultaneous voice & data).

• Availability is dependent on having a VoLTE-capable device, correct SIM provisioning, and LTE network coverage. • Subscribers will need to enable VoLTE on their handset and network provisioning will be required.

2. Charges & Billing

• VoLTE calls are generally billed as normal voice calls, not data usage, and use your existing voice bundle/minutes rather than data allowances (no extra data charges).

• No additional fees/costs for VoLTE beyond what you pay for your voice plan, as standard voice and call charges apply.

3. Service Use & Fair Use

• The service is intended to be used by individual subscribers for personal use.

4. Device & Network Limitations

• VoLTE availability is tied to BTC’s LTE network coverage and device compatibility; BTC does not guarantee service in all areas.

• Quality may vary due to network conditions and handset settings.

5. Roaming

• For VoLTE roaming, charges and conditions for roaming calls apply and differ from local usage, often dependent on partner networks abroad.

6. Changes & Discontinuation

• BTC reserves the right to change or withdraw VoLTE features, with or without notice, as tech or business needs evolve.
