FAQ — By the Gig for 1 line

How much is By the Gig for 1 line?

By the Gig runs $15.00/mo total for 1 line. The pricing breakdown above shows totals across all line tiers XFINITY Mobile offers.

Is a single line on By the Gig a good deal?

By the Gig at 1 line costs more per line than 2+ line tiers because the multi-line discount doesn't apply. If you're a single user, compare against MVNOs (Mint, Visible, Cricket) which often beat single-line carrier pricing for similar coverage.

Can I add more lines to my By the Gig plan later?

Yes — XFINITY Mobile lets you add lines mid-plan with prorated billing. The per-line price drops automatically as you cross line-count thresholds (typically at 2, 3, and 4 lines). Removing lines is also straightforward with no ETF on no-contract plans.

Does By the Gig include hotspot for 1 line?

Hotspot allowances on By the Gig are typically per-line (each line gets the published hotspot allowance). Check the plan-detail page for the exact GB; most premium unlimited plans include 25–60 GB per line at high speeds, dropping to slow speeds afterward.

What's the activation cost for 1 line on By the Gig?

XFINITY Mobile typically charges a one-time activation fee per line ($25–$45/line is common). The pricing breakdown above does not include activation; budget for it on your first bill.

Our takeEditorial
$15/GB on Verizon makes sense only for a phone that barely touches cellular - a single streaming hour changes the math fast.
UpPhone Team
The Optimist
“For a WiFi-first device that needs a backup signal, paying only for what you use is the honest pricing model.”
— the angel on your shoulder
The Cynic
“Not being able to manage this plan in the app in 2026 is a customer support nightmare waiting to happen.”
