I don’t have access to live tools in this turn, so I can’t fetch current streaming promotions or trial details directly right now. However, I can share practical, policy-respecting ways to watch Big Ten Network (BTN) or Big Ten Plus (B1G+) legally and often at low or no cost, plus common pitfalls to avoid. Direct answer

• BTN/B1G+ can be watched legally through several paid options, including official apps and services that carry BTN/B1G+. Free access generally comes only via trial offers or campus- or provider-specific accommodations, not as a universal free option.
• If you’re aiming for no out-of-pocket cost, your best legal routes are trial periods (if available) from streaming services that carry BTN/B1G+ and then cancel before the trial ends, or using campus-affiliated access when available.

Options to consider

• Free trials via streaming platforms: Some live TV streaming services offer BTN/B1G+ as part of their package and occasionally run free trial promotions (typically 7 days). Check the current promotions on services like Hulu with Live TV, YouTube TV, FuboTV, or DIRECTV STREAM to see if BTN/B1G+ is included and whether a free trial applies.
• Campus access: Some universities offer BTN/B1G+ access to students and staff through campus networks or VPNs. If eligible, this can provide legitimate access without personal subscription costs.
• Cable or satellite bundles: If there’s a current pay TV subscription, many providers provide BTN/B1G+ access through the provider’s apps (e.g., FOX Sports app login or provider-specific streaming). This isn’t free, but it may be included in an existing bundle you already pay for.
• BTN+ standalone options: BTN+ (the dedicated service for Big Ten content) sometimes has its own subscription options, sometimes with free trials or bundled promotions. Availability and pricing change, so verify current offers on the official service.

What to watch out for

• Avoid unofficial streams or promo schemes that promise “free Big Ten Plus” without legitimate authorization. These are often illegal or unsafe and can compromise devices or data.
• Be cautious with “free trial tricks” that require payment details and hope for a refund; read the terms carefully to understand cancellation windows and potential automatic renewals.
• If a promo sounds too good to be true (e.g., “free for life” or “free forever”), it’s almost certainly not legitimate.

If you’d like, specify your country or region and whether a campus affiliation might apply, and I can tailor a plan using current, reputable options and step-by-step setup guidance.
