In the ever-competitive world of prepaid wireless plans, two MVNOs (Mobile Virtual Network Operators) on T-Mobile’s network are vying for your attention with aggressive introductory offers. Tello Mobile and Flex Mobile have both launched promotions that echo the Mint Mobile playbook, offering steep discounts for new customers who prepay for three months. Tello’s “Super Saver” deal gets you 35GB for $15/month, while Flex Mobile’s promo offers 15GB for the same price. But which one is the better pick? Let’s break it down and crown a winner.
Tello vs Flex Mobile $15 Phone Plans
Tello Mobile’s Super Saver Deal
Tello Mobile’s latest promo, running from April 16 to April 30, 2025, slashes its flagship 35GB plan to $15/month (normally $25/month) when you prepay for three months. Taxes and fees are extra, so expect a slight bump at checkout. This plan is packed with features:
- 35GB of 5G data per month, throttled to 2G speeds after the cap
- Unlimited talk and text
- 5GB for mobile hotspot
- Free international texting
- Free calls to over 60 countries
After the three-month promo, you can renew at the regular $25/month rate, switch to another Tello plan, or port out to another provider. Tello, part of the Keep Calling family since 2015, has a solid track record and over 100,000 subscribers as of 2020.
Flex Mobile’s Promotional Offer
Flex Mobile, a newer player launched in 2024 by Excess Telecom, is offering a 15GB plan for $15/month (normally $27/month for three months or $29/month monthly) when you prepay for three months. Like Tello, taxes and fees are added at checkout, despite a homepage claim of “no hidden fees.” Here’s what you get:
- 15GB of 5G data, reduced to 128Kbps after the cap
- Unlimited talk and text
- eSIM-only (requires an eSIM-compatible phone)
- No clarity on hotspot usage or video streaming resolution
Post-promo, you can continue monthly, prepay another three months, or switch to an annual plan ($25/month for 15GB). Flex Mobile also offers a 5GB plan for as low as $14.08/month (annually) and a 25GB plan for $37.42/month (annually). Refunds are possible within 7 days, but the policy is vague and not guaranteed.
Head-to-Head Comparison
Let’s stack these plans side by side to see how they measure up:
| Feature | Tello Mobile | Flex Mobile |
|---|---|---|
| Promo Price | $15/month (3 months prepaid) | $15/month (3 months prepaid) |
| Regular Price | $25/month | $27/month (3 months) or $29/month |
| Data Allowance | 35GB 5G | 15GB 5G |
| Post-Cap Speeds | 2G | 128Kbps |
| Hotspot Data | 5GB included | Not specified |
| International Features | Free texting, calls to 60+ countries | None |
| eSIM Requirement | No (physical SIM or eSIM) | Yes (eSIM-only) |
| Taxes & Fees | Extra | Extra (despite “no hidden fees” claim) |
| Refund Policy | Not specified | 7 days, vague and not guaranteed |
| Promo Duration | April 16–30, 2025 | Not specified |
| Company Experience | Since 2015, 100k+ subscribers | Since 2024, newer player |
Key Differences
- Data Allowance: Tello’s 35GB dwarfs Flex Mobile’s 15GB, making it a better fit for heavy data users like streamers or remote workers.
- Hotspot Support: Tello explicitly includes 5GB for hotspot use; Flex Mobile doesn’t mention it, leaving tethering capabilities unclear.
- International Features: Tello’s free international texting and calls to over 60 countries are a huge perk for those with global connections. Flex Mobile offers no such features.
- eSIM Requirement: Flex Mobile’s eSIM-only setup limits compatibility, while Tello supports both physical SIMs and eSIMs, offering more flexibility.
- Transparency: Flex Mobile’s “no hidden fees” claim is misleading since taxes are added at checkout. Tello is upfront about extra taxes and fees.
- Post-Promo Value: Tello’s regular $25/month for 35GB is competitive with other MVNOs like US Mobile. Flex Mobile’s $25/month (annual) for 15GB is less compelling when competitors offer more data for the same price.
The Verdict: Tello Mobile Wins
For most users, Tello Mobile’s Super Saver deal is the clear winner. The 35GB of 5G data, hotspot support, and international features make it a powerhouse for the price, especially for those who need robust connectivity at home or abroad. Its flexibility with SIM options and established reputation further sweeten the deal. While Flex Mobile’s offer isn’t bad, its lower data cap, eSIM-only restriction, and lack of clarity on hotspot and international features make it less versatile. Plus, the misleading “no hidden fees” claim and vague refund policy erode trust.
If you’re a light data user with an eSIM-compatible phone, Flex Mobile’s 5GB plan at $14.08/month (annually) might be worth a look after the promo. But for the introductory offer, Tello’s plan delivers unmatched value.
Why This Matters
These promos reflect a broader trend of MVNOs offering $15/month plans to lure new customers, following Mint Mobile’s lead. With competitors like Boost Mobile (30GB for $15/month) and FreeUp Mobile (5GB for $15/month) in the mix, the prepaid market is heating up. Tello’s deal stands out as one of the most generous, especially on T-Mobile’s reliable network.
Act Fast!
Tello’s Super Saver deal is only valid until April 30, 2025, so don’t wait too long. If you’re ready to make the switch, head over to Tello Mobile to grab this offer. For Flex Mobile, check out their site at Flex Mobile, but be prepared for potential checkout surprises.
