Xfinity postpaid plans compared
We compare Xfinity’s two current postpaid plans, Mobile Select and Mobile Plus, for US households looking to combine their home internet and phone service.
Both require Xfinity Internet to sign up, so your choice also depends on whether you have or plan to get its home connection.

How much an Xfinity postpaid plan really costs
An Xfinity postpaid plan starts at $30/month for one line with qualifying Xfinity Internet, before taxes, fees, and device payments.
Adding lines doesn’t lower the price per line: Mobile Select stays at $30/month per line, and Mobile Plus stays at $45. Here’s how that adds up for one to four lines.
| Number of lines | Total monthly cost |
|---|---|
| 1 line | $30-45 |
| 2 lines | $60-90 |
| 3 lines | $90-135 |
| 4 lines | $120-180 |
Ranges run from all lines on Mobile Select to all lines on Mobile Plus. Prices include the qualifying Xfinity Internet customer discount; internet service, taxes, fees, and device payments are extra. Temporary promotional credits are excluded.
Roaming costs depend on your plan and where you travel. Current Mobile Select and Mobile Plus plans include roaming in 215+ destinations, with 10 GB of high-speed data per billing cycle, followed by speeds of up to 14 Mbps at no extra charge.
Cruise ships and airplanes are excluded; connecting to onboard cellular networks may incur additional pay-as-you-go charges.
If you keep an older Unlimited or By the Gig plan, Global Travel Pass costs $10 per line per day, adding $70 for seven days of use to your monthly bill. Each pass includes 5 GB of high-speed data, followed by reduced 3G speeds.
Before traveling, it’s worth understanding how Xfinity Mobile roaming works abroad, especially if your itinerary includes several countries.
For a simple way to stay connected during international travel, Holafly Plans offers one eSIM, coverage in 160+ destinations, and no additional roaming charges. Options with unlimited data and hotspot sharing let you navigate new cities, join work calls, and connect your laptop without buying a new package for every country.
These charges and conditions can affect what you pay beyond your monthly plan:
| Cost | What to expect |
|---|---|
| Taxes and fees | Additional charges vary by location and service. |
| Home internet | Xfinity Internet is billed separately from your mobile plan. |
| Activation fee | Standard fee of $25 per line; promotions may apply. |
| Device financing | Monthly phone installments, minus any applicable device credits. |
| First-year offer ending | The qualifying line increases by $30/month after its 12 monthly promotional credits end, at current regular rates. |
| Optional device protection | $9-19/month on Mobile Select, depending on the device. Included with Mobile Plus. |
Stay connected abroad with Holafly Plans
When your time abroad stretches beyond a short vacation, you need data for finding an apartment, joining work calls, and navigating unfamiliar streets.
Holafly Plans gives you ongoing coverage in 160+ destinations through one eSIM, with no additional roaming charges.
Choose Light with 25 GB of monthly data or Unlimited with unlimited data. Both include hotspot sharing to connect your laptop or tablet, plus 24/7 support from real people whenever you need help.
Your plan renews automatically, keeping you connected without buying another package each month, and you can cancel renewal anytime for the flexibility to stay as long as you need.
For extra support beyond your connection, the Holafly Ultra Plan includes everything in Unlimited, plus flight claim, luggage protection, doctor chat, mental wellbeing, and support 24/7. If your flight is disrupted, your bags go missing, or you feel unwell abroad, you’ll have help handling the situation, giving you greater peace of mind during longer stays away from home.
For a shorter vacation with fixed dates, a single-trip Holafly eSIM provides coverage for your destination and travel days.
Always On is included, providing 1 GB of monthly backup data after your main plan is ended or cancelled. All you need to do is to keep your eSIM installed. The allowance refreshes every 30 days at no extra cost.
Which Xfinity postpaid plan should you choose?
The right Xfinity postpaid plan depends on how you use your phone, rather than automatically choosing the highest tier. Consider how often you’re away from Wi-Fi, how much hotspot data you need, and whether you want device protection included.
| User type | What fits | Why |
|---|---|---|
| Light user, mostly on Wi-Fi | Mobile Select | Lower monthly rate, with 50 GB of priority data. |
| Heavy streamer or hotspot user | Mobile Plus | Unlimited priority data, 4K streaming, and 50 GB of high-speed hotspot data. |
| Family of 3–4 lines | Mobile Select, with Plus where needed | Select costs $30 per line; choose Plus for members who need its additional benefits. |
| Occasional traveler | Mobile Select | Roaming in 215+ destinations is included on both tiers. |
| Long-stay traveler or expat | Mobile Select + Holafly Plans | Keep your US number while using a separate monthly data plan abroad. |
Before an extended stay, check how keeping, suspending, or canceling your home line affects your number and device payments.

|---|---|---|
| Billing | Pay before use; plan taxes and fees included | Monthly billing; taxes and fees extra |
| Credit check | Not required | Eligibility based on a soft credit check or payment history |
