Common questions
$25 Build Your Own Plan vs $18 Unlimited Plus — FAQ
Which plan is cheaper after taxes, the $25 Build Your Own Plan or $18 Unlimited Plus?
The $18 Unlimited Plus is the cheaper of the two at $18 per month versus $25, and because both add taxes and fees on top the gap holds after tax. Multi-line and autopay discounts can still shift the math, so check each plan's pricing for your situation. The cost breakdown on each plan page estimates the all-in total for your state.
Which plan gives you more data, the $25 Build Your Own Plan or $18 Unlimited Plus?
The $25 Build Your Own Plan offers more high-speed data, with the $25 Build Your Own Plan at 50GB and the $18 Unlimited Plus at 40GB. More headroom matters most if you stream, tether, or travel without WiFi; lighter users may never reach either cap. Check the deprioritization and post-cap speed rows in the feature table, since those shape real-world speeds once the network is busy.
Do the $25 Build Your Own Plan and $18 Unlimited Plus run on the same network?
Yes, both plans run on the LTE, 5G network, so coverage and tower access are effectively identical between them. Where they can still differ is data prioritization: a carrier's own plan often gets premium priority while an MVNO riding the same towers may be deprioritized during congestion. Compare the priority and deprioritization rows to see how each is treated at peak times.
Can I keep my number when switching between the $25 Build Your Own Plan and $18 Unlimited Plus?
Yes. US carriers are required to support number portability, so you can transfer your existing number to either plan when you switch. Start the move from the new carrier and keep the old line active until the port completes, which usually takes from a few minutes to a couple of hours. You will typically need your account number and a transfer PIN from your current provider to authorize the switch.
