How to Read the "Network Bands and Model Variants" Fields

What is this section about?

This section details the cellular frequencies (bands) the phone's hardware supports and helps identify specific hardware variants. How to find it: By default, this information is hidden to keep the report clean. To see it, scroll down to the GENERAL INFO section and click on "Show more" → "Full device specification".

Full device specification expanded

The table will expand, and you will see:

  • Network Support: Detailed lists of 2G, 3G, 4G, and 5G frequency bands built into the phone's hardware.
  • Hidden Regional Codes: Often, the specific regional model number (like A3717 in the example) is appended to the end of the band lists.
Network bands and variant code example
Expand the specifications to see the supported network bands and the specific variant code they apply to.

What do the 2G/3G/4G/5G bands and codes mean? The numbers listed in these rows (like 1, 2, 3, 20, etc.) are the exact physical radio frequencies the phone's built-in modem can connect to. At the very end of these band lists, you will often see a short alphanumeric code after a dash (for example, - A3717 or - GKWS6). This code represents a specific hardware variant of the phone.

Why you might not see the bands for your specific device: A single phone model (like the "iPhone 18 Pro Max") is often manufactured in several different hardware variants to accommodate different cellular networks around the world. Because of this, there are usually more variant codes in existence than what is displayed in the band breakdown. The database might only show the frequency bands for one specific variant (like the A3717 in the example). If your phone's variant code is different from the one listed next to the bands, the frequencies shown might not perfectly match your actual device.

What should you do?

  1. Find your exact variant code: Since menus vary by brand (Apple, Samsung, Google, etc.), look for a specific alphanumeric model code (e.g., A3717 or SM-S911B) in these common places:
    • In the device settings (typically under Settings > About Phone, Device Info, or Regulatory Labels).
    • Printed on the barcode sticker of the original box.
    • Engraved in tiny text on the back cover of the phone. (If you are buying the phone online, ask the seller to check these places and send you the exact code.)
  2. Compare the codes: If the code you found matches the one shown in the report, you can directly compare the listed bands with your local carrier's frequencies to ensure full 4G/5G coverage.
  3. Double-check if needed: If your code doesn't match the one in the report, we highly recommend searching online for the supported bands of your specific variant code to be absolutely sure it will work with your network.

What this data will NOT show you: The network characteristics in the report are strictly original factory specifications. They do not guarantee that:

  • The phone is carrier-unlocked: Network info does not confirm unlock status. A device might support every frequency band in the world but still be software-locked to a specific carrier.
  • The phone is not blacklisted: Network specs have absolutely nothing to do with whether the device has been blocked or blacklisted.
  • Current location: These specs indicate how the phone was manufactured, not where it is being used right now.

What if the fields are empty or say "Unknown"? Just like with other additional specs, this is a completely normal and expected result. Most often, it means that the database simply doesn't have a detailed breakdown of frequencies for this specific model. Missing fields do not indicate a problem with the device itself.

What to check next?

  • Do the network bands match your carrier? Now check the Warranty and Service section to see if the phone still has official manufacturer support.
  • Is the phone completely clean? Even if it supports your local network, it won't connect if it's blocked. Always run a Blacklist check before purchasing.
