What You Get with MDS Crew Sim
Talk & Call Rules
The MDS Crew Sim provides unlimited calling inside the USA. Whether you’re calling family, scheduling dockside services, or staying in touch with the captain, you can place as many calls as you need with no limits.
There are a few important details:
  • Inside the USA: International calls are not supported. For international calls, use WhatsApp or other internet-based apps.
  • Outside the USA: You can still make calls to USA numbers, billed at $0.25 per minute. Again, we recommend WhatsApp for international communications to avoid charges.
  • Upgrade Starlink Direct to Cell service and say goodbye to cellular dead zones.
This makes the plan simple: Unlimited USA calls while you’re working domestically, and low-cost calls back to the USA when you’re abroad.

Unlimited Text Messaging
The MDS Crew Sim includes Unlimited SMS inside the USA. Crew members can send and receive unlimited text messages without restrictions, keeping communication easy and predictable.

Unlimited Data & Hotspot

For data usage, the MDS Crew Sim delivers unlimited data inside the USA. Whether you’re streaming, browsing, or video chatting, you won’t need to worry about running out of data.
Details include:
  • 200 GB threshold: After 200 GB of usage in a billing cycle, your service may be slowed depending on local tower congestion. In most cases, crew notice no impact.
  • 5 GB of high-speed tethering: Hotspot use is included, with up to 5 GB at full speed for laptops, tablets, or other devices. After 5 GB, hotspot data may run at reduced speeds. In most cases, crew notice no impact.
This makes the MDS Crew Sim perfect for crew who not only need unlimited phone data, but also reliable tethering to keep other devices online.
Flexible Prepaid Plan
The MDS Crew Sim is a prepaid service—you pay in advance every month, with no surprises.
  • Price: $49.99 per month, plus tax.
  • Billing date: Charged monthly on the service start date.
  • Minimum service term: 30 days.
  • Deactivation rule: You must request cancellation at least 5 days before the billing date to avoid automatic renewal.
  • No long-term contracts: Service continues month-to-month until cancelled.
  • Upgrade to T-Satellite service and say goodbye to cellular dead zones. Additional $15 per month, plus tax.
This makes the plan flexible for yacht crew who may only be in the USA for a few months at a time. You’re not tied to annual commitments, and you can cancel when your schedule changes.

Easy Setup – SIM or eSIM

We designed the MDS Crew Sim to work with nearly all modern devices.
  • Supports physical SIM and eSIM. If your device supports eSIM, you can activate without needing a card shipped.
  • Works with unlocked phones. Any GSM-compatible unlocked phone will work with the T mobile sim card.
  • Number transfer supported. You can transfer any existing number that is not already active on T mobile.
  • Activation timing: Activations cannot be processed on weekends, and it may take up to 24 hours for a new SIM or eSIM to be active.
Setup is simple: choose SIM or eSIM, activate, and you’re ready to go with unlimited USA service in minutes.

Why Choose MDS Crew Sim Over Retail SIMs?

Consumer retail SIMs and prepaid plans may look similar, but they come with restrictions that don’t work for yacht crew.
  • Retail SIMs throttle data after 18 GB. Even if they advertise “unlimited,” speeds drop drastically after 18GB usage cap.
  • Hotspot often blocked. Many consumer SIMs disable or severely limit tethering.
  • International calling issues. Crew often need clear rules, and retail SIMs bury restrictions and extra charges in the fine print.
With MDS Crew Sim, you get:
  • Unlimited Talk, Unlimited Text, and Unlimited T Mobile 5G Data, in USA.
  • 0.25 per min Talk to USA, Unlimited Text, and 5GB 5G Data in Canada and Mexico.
  • 0.25 per minute calls to USA from Europe.
  • 50 GB of high-speed T Mobile Priority Tethering in USA.
  • No outbound international calls.
  • No long term contracts, no hidden restrictions.
  • 30 day minimum term.
  • Upgrade to Starlink Direct to Cell service and say goodbye to cellular dead zones. Additional $15 per month, plus tax
For yacht crew, the MDS Crew Sim is the only plan designed with your lifestyle in mind.
