Apple: Dual SIM Mode Prevents iPhone 12 Users From Accessing Full 5G Speeds, At Least For Now
Apple’s iPhone 12 and iPhone 12 Pro both go on sale this coming Friday, October 23 but we’re still learning things about the phones as we get closer to the big day. According to one document it seems that the new iPhones won’t support full-speed 5G when operating in dual-SIM mode.
The document in question appears to be a training document that has been made available to Apple Store employees.
On the subject of 5G working in dual-SIM mode, the document says the following:
“Does 5G work with Dual SIM?”
When using two lines in Dual SIM mode, 5G data isn’t supported on either line and will fall back to 4G LTE. If customers are using eSIM only and are on a 5G-supported carrier and service plan, they’ll have 5G access.
Based on that it would appear that only 4G speeds will be available if either of the lines isn’t 5G-capable.
However, as MacRumors, notes it seems that one Reddit user thinks this will change in the future. They say that a software update, coming later this year, will enable 5G support when dial SIM support is being used.
This is the first time Apple has sold any iPhone with 5G support and it will surely want to make sure that everyone can make the most of it. Especially considering how heavily the company was leaning on the 5G capabilities during the iPhone 12 announcement event last week.
