If you’ve ever noticed that your roaming SIM’s speed is struggling to pick up much speed while your mobile phone is performing quite well on the same network, there could be a few reasons behind this discrepancy. One of the primary factors is the allocation of different frequency bands for data transmission.

Decoding the Frequency Bands

LTE networks utilize frequency bands to transmit data, with lower frequency bands being slower and higher frequency bands being faster. Your roaming SIM and mobile phone may be randomly assigned to different bands, depending on various factors such as network traffic, location, and device capabilities.

The Trade-off between Speed and Coverage

Lower frequency bands, such as 800MHz, generally offer better coverage and can penetrate walls and other obstacles more effectively. However, they also transmit data at slower speeds compared to higher frequency bands like 2100MHz and 2600MHz.

Manual Band Selection for Optimal Performance

In certain scenarios, manually selecting a specific frequency band for your roaming SIM can enhance its performance. If your roaming SIM is connected to the lowest frequency band (800MHz) while you’re relatively close to a cell tower with minimal obstructions, switching to a higher frequency band can significantly boost your data speeds.

Remote Area Considerations

On the other hand, if you’re in a remote area with limited signal coverage, switching to a lower frequency band can help your roaming SIM connect to a signal from a longer distance, even if it means sacrificing some speed.

Optimizing Your Roaming SIM Experience

To further optimize your roaming SIM experience and minimize speed discrepancies compared to your mobile phone, consider the following tips:

  1. Positioning: Place your roaming SIM in a central location with minimal obstructions between it and the cell tower.
  2. Firmware Updates: Keep your roaming SIM device’s firmware up to date, as updates often address performance enhancements and bug fixes.
  3. Wired Connections: For demanding devices like gaming consoles or streaming players, connect them directly to the roaming SIM device via Ethernet cables for a more stable connection.
  4. Reliability over Speed: If you prioritize reliable connectivity over maximum speed, consider opting for a lower frequency band, especially in remote areas.

By understanding how frequency bands influence data transmission and following these optimization strategies, you can maximize the performance of your roaming SIM and enjoy a seamless internet experience, even while experiencing varying speeds compared to your mobile phone.
