What is going on with Union’s Network?

As Union moves towards completing the installation of its new network and the inevitable shutdown of 3G, unforeseen complications have presented themselves, as they often do with any sort of major undertaking

Among these complications are increased requirements to ensure the compatibility of Samsung devices on Union’s network. As previously communicated, mobile devices must be VoLTE compatible to be supported on our network, though it is important to remember that the mobile device’s VoLTE compatibility is not the only requirement. Additionally, they require what’s known as carrier bundles to complete the process

Carrier bundles are better understood as software updates directly from the mobile device manufacturer. These specific updates synchronize the mobile device settings to Union’s network. Without them, the ability to make or receive phone calls while outside of Union’s immediate service areas is lost. As a consequence, many of you may have already experienced service issues related to this transition. Please know that Union is working hard with our partners to resolve this situation as quickly as possible

What is a SKU? and why it matters

It is important to note that every mobile device has a SKU (stock keeping unit) or Model Number which helps identify it. Every device on this list has an associated SKU that includes a “U1” which signifies that the mobile phone is “USA Unlocked”. Devices lacking the “U1” designation as part of the SKU are assigned differently and may not be eligible for the carrier bundle updates.

How do I know what SKU my phone has & where do I find it?

1. Open your phone's Setting

2. While in Settings locate the “About Phone” or “About Device” option

3. Select “About Phone” option. You may see the SKU listed as “Model Number”

a. Example SKU: SM-S90U1 (Samsung Galaxy S22)
