Another drawback of VoLTE is its limited availability in current mobile networks. Only a few mobile operators have deployed VoLTE networks; even in those areas, the coverage might be restricted.
This means that users in many regions may not have access to the advantages offered by VoLTE, limiting its usability and benefits.
Battery Drain Concerns
VoLTE can hurt battery life. Compared to traditional 2G and 3G networks, VoLTE consumes more power due to its complex signaling process.
This higher power requirement can result in significant battery drain. Additionally, the simultaneous use of data services during VoLTE calls can contribute to increased power consumption.
Users who frequently engage in lengthy VoLTE calls may need to carry spare batteries or power banks to ensure their devices remain adequately charged.
Increased Data Usage
VoLTE necessitates higher data usage compared to 2G and 3G networks. This is due to the packet-switched technology employed by VoLTE, which requires more data to transmit the same amount of information.
As a result, users who frequently utilize VoLTE for calls may need to opt for higher data plans to avoid exceeding their data usage limits. This additional data requirement could increase costs for users with limited data allowances.
Interoperability Challenges
VoLTE faces interoperability issues due to its use of a different signaling protocol than traditional networks. As a result, calls between different mobile operators or networks may not be fully compatible, potentially causing connectivity issues.
Moreover, VoLTE calls might not connect to traditional 2G and 3G networks, which can be problematic in areas with limited 4G LTE coverage.
