How compatible is the Honor X9d 5G with major U.S. networks?
The Honor X9d 5G has drawn attention from tech enthusiasts across the United States for its sleek design and solid mid-range performance. However, one major question remains for potential buyers — does the device work properly with major U.S. carriers like Verizon, AT&T, and T-Mobile? As global smartphone markets become increasingly interconnected, many consumers are exploring imported models. Yet, carrier support remains a critical factor when determining if a phone can perform reliably in the U.S.
Recent user testing and network analysis indicate that the Honor X9d 5G offers only partial compatibility with American cellular networks. This phone, designed primarily for Asian and European markets, was not officially certified for North American use. As a result, its network band coverage does not fully align with the bands used by U.S. carriers. While it may connect in certain areas, performance varies depending on the region and the carrier’s available frequencies.
For T-Mobile users, the Honor X9d 5G delivers the best chance of stable connectivity among the major carriers. T-Mobile operates a wide range of 4G LTE and sub-6GHz 5G bands, some of which overlap with the frequencies supported by the X9d. Users in major metropolitan areas may experience decent data speeds and network coverage, especially on low-band 5G. However, due to the device’s limited support for some of T-Mobile’s high-frequency and mid-band 5G channels, overall performance may still fall short compared to officially supported devices.

AT&T presents a more complicated scenario. Although the Honor X9d 5G can access a few of AT&T’s LTE bands, many critical frequencies — including those responsible for nationwide 5G coverage — are not supported. As a result, users may experience dropped connections, slower speeds, or complete network incompatibility in some areas. Moreover, AT&T’s network policies typically require device certification to enable full services like VoLTE and Wi-Fi calling. Since the Honor X9d is not officially certified for AT&T’s U.S. network, those advanced features may not function properly, even if the device connects.
Verizon compatibility is the most limited among the major carriers. Verizon’s network relies heavily on specific LTE and 5G bands that the Honor X9d does not support. In most cases, users attempting to use a Verizon SIM card with the device encounter restricted service, weak signal strength, or no connection at all. Verizon’s system also maintains strict certification requirements, preventing non-approved devices from activating fully. For these reasons, the Honor X9d 5G is not considered suitable for Verizon users in the United States.
Aside from frequency support, network features also influence real-world usability. Many imported models struggle with U.S.-specific network functions such as Voice over LTE (VoLTE), Wi-Fi calling, and carrier aggregation — features that improve call quality and data speed. The Honor X9d 5G, designed for regions with different network standards, does not guarantee these functions in the U.S. Without proper firmware and carrier approval, even users who manage to connect might face reduced performance and inconsistent reliability.
The device’s limited 5G support also affects its competitiveness in a market increasingly driven by next-generation connectivity. U.S. carriers use a complex mix of sub-6GHz and mmWave 5G bands to provide broad and fast coverage. Since the Honor X9d 5G was not engineered for those specific frequencies, users miss out on the fastest speeds and broadest signal range. This limitation becomes more noticeable as carriers continue to expand their 5G infrastructure nationwide.
For users still interested in using the Honor X9d 5G in the U.S., the safest choice is to pair it with T-Mobile or a T-Mobile-based MVNO (Mobile Virtual Network Operator). While coverage will not be perfect, it offers the best likelihood of maintaining consistent 4G and limited 5G service. It is also important to check with the carrier before activation, providing the device’s IMEI to confirm whether the phone can be added to the network. Buyers should also keep in mind that imported models may lack warranty coverage and future software updates tailored to U.S. requirements.
In summary, the Honor X9d 5G is not a fully compatible device for use across all major U.S. carriers. It may function adequately on T-Mobile in select areas but remains largely incompatible with Verizon and only partially functional on AT&T. Consumers considering this device for U.S. use should weigh the trade-offs carefully — especially if reliable connectivity, VoLTE support, or carrier warranty coverage is important. While the Honor X9d offers appealing design and performance features, its limited network compatibility makes it better suited for regions where it has official carrier certification rather than the U.S. market.
