Don’t put the “trash can” in the garbage bin!

Consequently, you’re all recommended to do the same thing if you’ve recently gotten a text message or email proposing a gateway upgrade “On Us.” If you haven’t just yet, but you know you’re still rocking a Nokia 5G21, you can give it a few more days or reach out to T-Mobile customer support to straight-up ask for a speed-improving freebie.
Worst case scenario, you’ll be denied the upgrade if you’re (somehow) not eligible. Best (and most frequent) scenario, you’ll be sent a zippy new gateway at home and asked to return your “trash can” by mail or in a nearby physical store. Yes, it’s that simple!
Double the speeds with no strings attached
At the risk of annoying you by saying this again, T-Mobile‘s latest 5G Home Internet upgrade will not cost you a dime. Not at the time of your order for your new gateway, not later via monthly payments or anything, and regardless of how little you currently pay for your service, your plan will not be changed in any way to “accommodate” this upgrade.
With the original (gateway) I was getting upper hundreds, 170, 180. I just pulled 336 per Ookla. Up speed doubled, from 10ish to 22.

Now, the speed boosts you’ll obtain once you replace the 5G21 with a G4AR or G5AR might vary from location to location and even depend on your luck, but a bunch of Redditors are claiming their improvements have been surprisingly substantial.
The setup process is also generally described as a walk in the park, requiring a simple switch of your SIM card from your old to your new blazing fast 5G gateway.
Consolidating T-Mobile’s 5G supremacy one small change at a time
In the grand scheme of the industry, what Magenta is doing with this product replacement is definitely not what one would call a big technological leap.
