Unfortunately, when you are using mobile phone browser to upload, the limitation is being set by the device browser (in this case the phone) -- this is due to capacity limitation of mobile devices.
BUT you can still make your mobile form allow more than one upload at a time by just adding multiple upload fields on it. So, the form user can use each upload field to upload files when they are using mobile browser.
We also recommend using InkFilepicker.io tool if you need upload capability on your form when used on mobile browsers. You can learn more about this in JotForm Apps
Hope this help. Inform us if you need more assistance.
