Verify 5G Standalone Status on Your iPhone

Included with iOS is the capability for iPhone to use T-Mobile’s 5G Standalone coverage in the US (in addition to other carriers globally). This option can offer speeds as fast as 3 Gbps using the power of carrier aggregation. Here’s how to ensure 5G Standalone is turned on with your iPhone and how to verify your cellular connection stats.

Introduction to 5G Standalone

T-Mobile officially launched its Ultra Capacity 5G SA network in November 2022, touting speeds up to 3Gbps. Initially, only flagship Samsung smartphones were able to take advantage of this network advancement. However, T-Mobile announced plans to expand its availability.

With iOS 16.4, the toggle to enable super-fast speeds arrived in iPhone Settings. 5G SA should be enabled by default for T-Mobile customers in the US. T-Mobile is currently the only stateside provider offering 5G SA, while Claro and Vivo have launched 5G SA for iPhone in Brazil. Other countries had this 5G variant available earlier.

T-Mobile’s Ultra Capacity 5G SA + carrier aggregation allows speeds of up to 3Gbps by merging multiple channels of mid-band 5G spectrum. However, it remains unclear which cities currently have access to 5G SA through T-Mobile, so testing the service is recommended.

Steps to Ensure 5G Standalone (SA) is Turned On

  1. Open the Settings App
    • Your iPhone should be running iOS 16.4 or later.
  2. Navigate to Cellular Settings
    • Choose Cellular.
  3. Select Cellular Data Options
    • Then tap on Voice & Data.
  4. Enable 5G Standalone
    • At the bottom, ensure the 5G Standalone toggle is turned on.

Checking Your 5G SA Connection Stats

After ensuring 5G Standalone is turned on, follow these steps to check your connection stats:

  • Run a Speed Test
    • This will give you an indication of the performance you’re achieving.
  • Enter Field Test Mode
    • Dial 3001#12345# and hit call.
    • This will provide specific details about your 5G connection and whether you’re getting Standalone service.
    • Look for SA next to connection_type.

Keep in mind that while T-Mobile tests have achieved speeds of up to 3.3Gbps, real-world performance will vary.
