What is Tello?
Tello is a T-Mobile MVNO (Mobile Virtual Network Operator) that launched in 2016 with a simple mission: let customers build their own phone plan instead of forcing them into preset tiers.
Unlike carriers that offer 3-4 fixed plans, Tello lets you choose your exact data, minutes, and text amounts – creating over 60 possible plan combinations. It's the "Subway sandwich" approach to wireless.
Key facts:
- Parent company: Tello (independent MVNO)
- Network: T-Mobile 4G LTE and 5G
- Founded: 2016
- Support: Phone, chat, and email
- Headquarters: Atlanta, Georgia
Tello Plans Breakdown
Tello offers two ways to get service: preset plans or build-your-own.
Tello's four preset plans: Unlimited $25, Economy $10, Value $14, Smart $19
Preset Plans
| Plan | Price | Data | Talk | Text |
|---|---|---|---|---|
| Data (Unlimited) | $25/mo | Unlimited* | Unlimited | Unlimited |
| Economy | $10/mo | 2 GB | Unlimited | Unlimited |
| Value | $14/mo | 5 GB | Unlimited | Unlimited |
| Smart | $19/mo | 10 GB | Unlimited | Unlimited |
*Unlimited plan includes 35GB of high-speed data, then reduced speeds
Build-Your-Own Plans
Tello's plan builder: slide to select data and minutes, price updates instantly
This is where Tello shines. Mix and match:
Data options: No data, 500MB, 1GB, 2GB, 4GB, 6GB, 8GB, 10GB, 15GB, or Unlimited (35GB high-speed)
Talk options: No minutes, 100 min, 300 min, 500 min, or Unlimited
Text options: Free (always included with any plan)
Example builds:
- Light user (WiFi mostly): 1GB + 100 min = ~$8/mo
- Moderate user: 5GB + Unlimited talk = ~$14/mo
- Data focused: 10GB + 300 min = ~$17/mo
- Data only (tablet): 5GB + No minutes = ~$10/mo
Why this matters: If you're a light user who mainly uses WiFi, why pay $25 for unlimited data? Tello lets you pay $8-10 for what you actually use.
Taxes and Fees Reality
Unlike Visible, Tello does NOT include taxes in their prices. Expect to add:
- State wireless taxes: $1-4 depending on location
- Federal Universal Service Fund: ~$0.50
- Total extra: Usually $2-4/month
A $25 "unlimited" plan will actually cost ~$27-29 after taxes.

Network Coverage and Speeds
Tello uses T-Mobile's network – the same towers as T-Mobile postpaid and other T-Mobile MVNOs like Mint Mobile.
T-Mobile coverage strengths:
- Strong in urban and suburban areas
- Best-in-class 5G deployment
- Excellent building penetration (low-band 5G)
T-Mobile coverage weaknesses:
- Rural coverage gaps (especially in Mountain West)
- Congestion in some metro areas
- Less reliable than Verizon in remote areas
Real-World Speed Tests
We tested Tello in various conditions:
| Location Type | Time | Download | Upload | Ping |
|---|---|---|---|---|
| Urban (low congestion) | 2 PM | 95 Mbps | 15 Mbps | 28ms |
| Suburban | 12 PM | 65 Mbps | 10 Mbps | 32ms |
| Urban (rush hour) | 6 PM | 25 Mbps | 6 Mbps | 38ms |
| Rural | Any | 15 Mbps | 3 Mbps | 65ms |
The deprioritization reality:
Like most MVNOs, Tello customers are deprioritized behind T-Mobile postpaid customers during congestion. However, T-Mobile's network is typically less congested than Verizon's, so the impact is often minimal.
Why Tello? Key Features
Why Tello? Nationwide 5G, fully customizable plans, family plans, and referral rewards
1. Build-A-Plan Flexibility
No other carrier matches Tello's customization. You're not locked into predefined tiers – you pick exactly what you need. Customize your plan based on your monthly needs and budget, and change it anytime.
Perfect for:
- Light users (mostly on WiFi)
- People with unpredictable usage
- Those who want to optimize every dollar
- Families where each member has different needs
2. Free International Calling
Free calls to 60+ countries including Canada, Mexico, and India – built into every plan
This is a massive perk that most carriers charge extra for. Say hello to your auntie in London or call your friends abroad – free international calls are included in every Tello plan with minutes.
Free calling to:
- Canada and Mexico (unlimited)
- India (unlimited)
- China, UK, Germany, France
- 60+ countries total
For anyone with family abroad, this alone can save $20-50/month compared to international calling plans from major carriers.
3. Nationwide 5G Coverage
Coast-to-coast wireless coverage on T-Mobile's network. Forget about dropped calls, loading issues, or slow data speeds. Unlike some budget carriers that charge extra for 5G, Tello includes T-Mobile 5G access on all plans at no additional cost.
4. Upgrade/Downgrade Anytime Free
Need to add more data? Or need to cancel a line? Do that any time, free of charge. Absolutely no penalties. You're in control of your phone plan.
5. Excellent Customer Service
Tello has some of the best customer service ratings in the MVNO space:
- Trustpilot: 4.5/5 stars (13,984+ reviews)
- BBB: A+ rating
- Support options: Phone, chat, and email (not chat-only like Visible)
6. Referral Program
Good friends pay off! Share your unique link to refer a friend, and you both get $10 Tello Dollars. There's no limit to how many friends you can refer – some users have built up significant credit just by sharing their experience.
Hotspot and Tethering
Every Tello plan includes hotspot, WiFi calling, international calls, and free plan changes
Tello includes mobile hotspot on all plans:
| Plan | Hotspot Data |
|---|---|
| Unlimited | 10GB dedicated hotspot |
| 2GB Economy | 2GB shared with phone |
| 5GB Value | 5GB shared with phone |
| 10GB Smart | 10GB shared with phone |
Key difference: The Unlimited plan gets a dedicated 10GB hotspot allowance, while other plans share hotspot with your phone data.
Important: Unlike Visible's unlimited hotspot, Tello's hotspot is capped. Heavy hotspot users might find this limiting – consider Visible if you need extensive tethering.
Is Tello Good for Families?
Yes! Tello offers family discounts that make it even more affordable:
Multi-line savings:
- 2 lines: 10% off
- 3 lines: 15% off
- 4+ lines: 20% off
Example family plan:
- 4 lines x $25 unlimited = $100/mo
- 20% family discount = -$20
- Total: $80/month for 4 unlimited lines
That's $20/line for unlimited data on T-Mobile's network. Hard to beat.
Security Assessment
Security is a key part of our 11-point scoring. Here's Tello's security posture:
| Security Feature | Tello | Industry Avg |
|---|---|---|
| 2FA available | ✅ Yes | ~60% offer |
| SIM PIN protection | ✅ Yes | ~70% offer |
| Data breaches | ✅ None | Many have had |
| Account security | Good | Varies |
Tello checks all security boxes: Both 2FA and SIM PIN protection are available – something Visible lacks. Combined with a clean data breach record, Tello is one of the more security-conscious budget carriers.
