▶ 📦 Calyx Institute Membership Levels
Calyx offers three membership levels with unlimited T-Mobile data. Choose the one that best fits your needs:
▶ Contributor - Franklin T10 Mobile Hotspot NOT RECOMMENDED
We do not recommend this plan. The Franklin T10 is a 4G LTE-only device. Carriers are actively phasing out 4G infrastructure in favor of 5G, which means speeds will continue to decline over time and the device will eventually stop working altogether. Your account is also permanently tied to this hardware — you cannot switch to a different device later. Choose the Sprout (SIM-only) plan instead for better performance, future-proofing, and hardware flexibility.
▶ Sustainer - MiFi X PRO 5G Hotspot
Pricing:
• First year: $750/year ($62.50/mo)
• Renewal: $500/year ($41.67/mo)
What's Included:
- MiFi X PRO 5G mobile Wi-Fi hotspot
- 2 Gbps max speed (5G/4G)
- Supports up to 32 connected devices
- WiFi 6 technology
- 8 hours battery life
- Can be tethered via USB-C
- 1 Gbps Ethernet port
- Can charge other devices
- Unlimited 5G/4G data
Best for: Users who are okay with medium speeds and only have a few devices to connect. Better than the Franklin T10 with 5G support and more device capacity.
⚠️ Important: Your account is permanently tied to this device. You cannot switch to different hardware later. If you need flexibility to change routers, choose the SIM-only plan.
▶ Sprout BYOD - SIM Card Only (Our Choice!)
Pricing:
• $500/year ($41.67/mo) or $150/quarter ($50/mo)

Best for: Users who want to use professional routers with external antenna support for maximum signal strength and performance.

▶ 📡 Boost Your Signal: External Antenna (Sprout Plan Only)
For the best performance, especially in areas with weak or moderate T-Mobile signal, we highly recommend installing an outdoor antenna:
Recommended: Waveform QuadPro Antenna
- Professional-grade 4×4 MIMO outdoor antenna
- Dramatically improves signal strength and speeds
- Weather-resistant design for outdoor mounting
- Compatible with GL-X3000, GL-XE3000, and most cellular routers
- Includes mounting hardware and cables
💡 Note: External antennas work best with the GL-X3000, GL-XE3000, or Peplink routers (SIM card only option). The included mobile hotspots may have limited or no external antenna support.
