Your family pays a large monthly bill for unlimited postpaid plans. A coworker pays a fraction of that for a prepaid plan and gets service on the same network. How is that possible, and what is the catch?
Mobile virtual network operators (MVNOs) and prepaid brands have become a mainstream way to cut phone bills. They work well for many people — but there are trade-offs.
Key Takeaways
- MVNOs lease capacity on major carriers’ networks, so coverage is usually the same as the host network’s.
- Many MVNO and prepaid customers may be deprioritized during congestion, meaning slower data when networks are busy.
- You can usually keep your phone number when switching, using number porting.
- Check phone compatibility, unlock status, hotspot limits and international roaming before switching.
What is an MVNO?
An MVNO is a mobile carrier that does not own its own network infrastructure. Instead, it buys access to a major carrier’s network and sells service under its own brand. Some MVNOs are owned by the major carriers themselves; others are independent.
Prepaid plans — where you pay in advance each month or for several months — are offered by both MVNOs and major carriers.
Why prices are lower
MVNOs and prepaid plans often cost less because they:
- Have fewer retail stores
- Spend less on marketing
- Offer fewer perks, such as streaming bundles
- Sell discounted multi-month plans
- Use deprioritized network access
Deprioritization
During network congestion — at busy times or in crowded places — carriers may prioritize traffic from certain customers. Many MVNO and prepaid users are lower priority than postpaid customers. Most of the time, you will not notice. In congested areas, such as stadiums or busy downtowns, data speeds may slow.
Some plans also limit video streaming quality or hotspot data.
Coverage
Since MVNOs use major networks, coverage generally matches the host network’s coverage. Check the coverage maps of the host carrier for where you live, work and travel. In some cases, roaming agreements on MVNOs may differ from the host carrier’s postpaid plans.
How to switch and keep your number
- Check that your phone is unlocked. Phones bought on installment plans may be locked until paid off.
- Check compatibility using the new carrier’s website.
- Get your account number and transfer PIN from your current carrier. Many carriers let you generate a number transfer PIN online.
- Buy the new SIM or eSIM and follow activation instructions.
- Port your number. Porting usually happens within minutes to hours.
Do not cancel your old service before the port completes; canceling first can lose your number.
If you are paying off a phone through your current carrier, the remaining balance may become due when you leave, and promotional credits may stop.
Choosing a plan
Consider:
- Data needs: check your usage history to see how much you use.
- Hotspot use: some plans limit it.
- International calling and roaming: if you travel, compare options.
- Family plans: some MVNOs offer multi-line discounts.
- Customer service: online-only support may suit some users and not others.
- Multi-month pricing: paying for several months up front often lowers the monthly cost.
Who should consider switching?
MVNOs and prepaid plans work well for:
- Light to moderate data users
- People who use Wi-Fi most of the time
- Families looking to cut costs
- People who own their phones outright
They may be less suitable for people who:
- Need guaranteed high-priority data in congested areas
- Rely heavily on hotspot use
- Want in-person store support
- Value bundled perks
Frequently Asked Questions
Will my phone work on an MVNO? Most unlocked phones work if compatible with the host network.
Is MVNO service less reliable? Coverage is generally the same as the host network, but data speeds may be slower during congestion.
Can I switch back later? Yes, you can port your number again.
Do MVNOs support eSIM? Many do. Check before switching.
The bottom line
MVNOs and prepaid plans can deliver the same coverage at lower cost. Check coverage, phone compatibility and data needs, and make sure your number transfer completes before you cancel your old service.
