If our requirements are not met by your standard products, can customization be done?

The GRTSMS standard product has 4 built-in frequency bands and covers at least 2 operators. We also prioritize compatibility with operators with the largest user bases in target countries, so our standard products can meet the needs of most users. If you need additional bands to cover all frequencies for all operators, we can customize the machine to your needs. Each additional two bands will cost 5000 USDT. Note: Adding two carriers requires corresponding upgrades, such as amplifiers, multiplexers, or filters. As the device size increases, so does power consumption. For in-vehicle use, you need to consider whether the car's generator output can support the machine's power needs. It is generally recommended to pair it with an external power source.
