Understanding Network Compatibility for Your Custom Android Device

When it comes to purchasing a new phone or tablet, network compatibility is one of the most critical factors to consider. At SatComShop, we specialize in offering customized Android devices — from rooted phones to GrapheneOS and Ubuntu setups — tailored to fit your preferences. However, no customization matters if your device isn’t compatible with your carrier’s network.

In this guide, we’ll walk you through the essentials of network compatibility and how to ensure your device works seamlessly with your preferred carrier.

What is Network Compatibility?

Network compatibility refers to whether your phone or tablet can connect to a specific carrier’s network. Carriers operate on different frequencies and network technologies (GSM, CDMA, LTE, 5G). If your device doesn't support those frequencies, you might experience poor service or no service at all.

Key Factors to Consider

1. GSM vs. CDMA — Know the Difference

Historically, networks were divided into two major types:

GSM (Global System for Mobile Communications): Used by carriers like AT&T and T-Mobile.

CDMA (Code Division Multiple Access): Previously used by Verizon and Sprint.

However, with the rollout of LTE and 5G, these distinctions are blurring. Most carriers now support unlocked GSM devices. That said, knowing your carrier’s network type remains crucial, especially if you're using an older device.

2. Frequency Bands & LTE/5G Support

Each carrier operates on specific frequency bands. If your device lacks the necessary bands, your service quality may suffer.

AT&T and T-Mobile: Primarily use LTE bands 2, 4, 5, 12, 17, 66, and 71.

Verizon: Uses LTE bands 2, 4, 5, 13, and 66.

5G Networks: Newer devices should support bands n2, n5, n41, n66, n71, and more depending on the carrier.

At SatComShop, we ensure our customized devices support a wide range of frequency bands, but it’s essential to double-check with your carrier if you have a specific need.

3. VoLTE and VoWiFi Compatibility

Many carriers now require VoLTE (Voice over LTE) for calls. If your device lacks VoLTE support, you may experience call issues or find your device unable to make calls at all.

VoWiFi (Voice over Wi-Fi) is also crucial if you rely on Wi-Fi networks in low-signal areas.

When customizing your device, we focus on enabling these features where possible to ensure seamless connectivity.

4. Carrier Locking — Are You Free to Switch?

Some carriers lock devices to their network, restricting you from using another carrier until you meet specific conditions. Most of our devices at SatComShop are unlocked, meaning you have the flexibility to switch carriers as needed.

5. How to Check Your Device’s Compatibility

Before purchasing or activating a device, you can check compatibility using the following methods:

IMEI Checkers: Most carriers have an IMEI (International Mobile Equipment Identity) checker tool on their website. Enter your device’s IMEI number to confirm compatibility.

Carrier Support Pages: Refer to your carrier’s support page for a list of compatible devices.

At SatComShop, we are happy to help you verify compatibility before purchase to avoid any guesswork. Need to check if your device is compatible?
