Surface Pro 9 5G: 90 Days Free Data?
Yes, Surface Pro 9 owners with the 5G model get 90 days of free 5G service, but only if they activate a new eSIM through a participating carrier before the offer expires. This is a promotional trial, not a permanent free plan, and it applies only to the ARM-based Surface Pro 9 with 5G, not the Intel version.
Which Surface Pro 9 Models Qualify?
Microsoft sells two distinct Surface Pro 9 devices. The standard model uses Intel 12th-gen processors and has no cellular radio. The Surface Pro 9 with 5G uses the Microsoft SQ3 processor (based on ARM architecture) and includes a built-in eSIM and nano-SIM slot. Only the 5G model is eligible for the free data offer.
You can identify the 5G version by the model number (typically starting with “MQ� or “ES�) or by checking the SIM tray on the right edge near the volume buttons. The Intel model has no SIM tray at all.
How the 90-Day Free Service Works
The offer is a data-only trial, not a full phone plan. You get a set amount of high-speed data (often 100 GB in the US) for 90 days, after which the service ends unless you buy a paid plan. The trial is tied to the device’s eSIM, so you activate it through the built-in Windows Settings app rather than a physical SIM card.
Activation steps generally include:
- Open Settings > Network & Internet > Cellular.
- Select “Add eSIM� and follow the carrier’s activation flow.
- Choose the free trial option when prompted.
- Enter your email and create an account with the carrier.
The trial is available in the US only, and you must be 18 or older. You do not need an existing account with the carrier, but you will need to provide a valid email and possibly a credit card for identity verification (though you should not be charged during the trial).
Carrier Partners and Coverage
Microsoft partners with specific carriers for this offer. In the US, the primary partner is T-Mobile, but some Surface Pro 9 units sold through other retailers may include a trial from AT&T or Verizon. The exact carrier depends on where you bought the device and the current promotion.
Coverage follows the carrier’s normal 5G network. T-Mobile’s 5G covers a large portion of the US, but rural areas may fall back to 4G LTE. The trial includes only data; you cannot make voice calls or send SMS with the trial SIM. For calls, you would use a VoIP app like Skype or Teams.
How to Activate Your Free Trial
If your Surface Pro 9 with 5G came with the offer, the activation is mostly digital. Here is the typical process:
- Fully charge the device and connect to Wi-Fi for the initial setup.
- Go to Settings > Network & Internet > Cellular.
- Click “Add eSIM� and select “Download a SIM profile.�
- Choose your carrier from the list (or enter the activation code if provided).
- Follow the on-screen prompts to create an account and confirm the trial.
- Once activated, you’ll see the signal bars in the taskbar. You can then disconnect from Wi-Fi and use cellular data.
If you encounter an error, make sure your Windows is fully updated, as the cellular driver may need a recent patch. Also verify that your device is not carrier-locked; Surface Pro 9 units sold directly by Microsoft are unlocked, but some retailer versions may be locked to a specific carrier.
Common Problems and Fixes
Users report a few frequent issues with the 90-day trial:
- eSIM not showing up: Restart the device, then check Settings > Network & Internet > Cellular > eSIM. If it still fails, run the “Network reset� option in Settings.
- No signal after activation: Toggle airplane mode on and off, or remove and re-add the eSIM profile.
- Trial not offered: The offer may have expired. Check the Microsoft Store page for your device model or contact the carrier directly.
- Slow speeds: The trial likely caps at a certain speed (often 5G UC or LTE), and after a data threshold (e.g., 100 GB), speeds may be reduced to 3G levels.
If you bought a used Surface Pro 9 with 5G, the previous owner may have already used the trial. The offer is tied to the device, not the Microsoft account, so a second activation is not possible.
What Happens After 90 Days?
Once the trial ends, the eSIM profile is deactivated. You will lose cellular data until you purchase a new plan from the carrier. You can do this through the same Settings page, choosing a prepaid or postpaid data plan.
Alternatively, you can insert a physical SIM from any carrier that supports the Surface Pro 9’s frequency bands. The device is unlocked, so it works with GSM carriers like T-Mobile and AT&T, and also with Verizon’s 5G (though Verizon may require you to add the device’s IMEI to your account).
If you do not want to pay for cellular data, you can simply continue using Wi-Fi. The 5G radio does not drain battery when unused, and you can disable it in Settings to save power.
Costs and Alternatives
The 90-day trial is free, but after that, data plans from US carriers typically cost $10–$20 per month for a few gigabytes, or $30–$50 for unlimited. You can also use a mobile hotspot from your phone, which is often cheaper if you already have a phone plan with hotspot data.
Another alternative is to use a third-party eSIM service like Airalo or Holafly, which offer prepaid data plans without a contract. These are especially useful for international travel, though they may not support the Surface Pro 9’s specific 5G bands.
Before buying a plan, check the coverage map for your area. 5G is not available everywhere, and if you are in a rural zone, a 4G LTE plan might be more reliable and cheaper.
Frequently Asked Questions
Is the 90-day free 5G service available in my country?
The offer is currently available in the United States only. Microsoft has not announced similar trials for other regions. If you bought a Surface Pro 9 with 5G outside the US, you can still use a physical SIM from a local carrier, but you will not get the free trial.
Can I use the free trial for voice calls?
No, the trial is data-only. You cannot make traditional phone calls or send SMS. You can use internet calling apps like Skype, WhatsApp, or Teams, which work over the data connection.
Does the trial work on the Intel Surface Pro 9?
No. The Intel model does not have a cellular modem, so it cannot connect to 5G at all. The free trial is exclusively for the Surface Pro 9 with 5G (SQ3 processor).
What if I already have a T-Mobile account? Can I add the trial to it?
Yes, you can log in with your existing T-Mobile ID during activation, but the trial is separate from your main account. It will not affect your current plan, and you will not be charged. After the trial, you can choose to add the Surface to your existing plan or keep it separate.
How much data do I get in the 90 days?
In the US, the trial typically includes 100 GB of high-speed data. After you use that amount, speeds are reduced to 3G levels (around 1 Mbps) for the remainder of the 90 days. You can check your usage in Settings > Network & Internet > Cellular > Data usage.
Can I extend the trial or get another one?
No. The offer is a one-time promotion per device. You cannot extend it, and you cannot get a new trial by resetting Windows or changing your Microsoft account. After the trial, you must purchase a paid plan to continue using cellular data.
