Please note that the 5G function depends on the generations/models/regions of the iPhone.
You can refer to Support bands to continue. Under the existing test conditions, iPhone 13 mini (A2628) can be connected to
- 38 (TD 2600)
- 39 (TD 1900)
- 42 (TD 3500)
(Those are the bands provided by ORS)
iPhone's 5g functionality testing is restricted. The ORS provides 5G SA (stand-alone) instead of 5G NSA (non-stand-alone) while in Europe, 5G SA is not a common use case, so there is no compatible iPhone for us to complete the test. However, we suggest that you may purchase the compatible iPhone from mainland China, where the 5G SA is wildly used and the 5G SA is applied to iPhones.
