Why ca n’t you have three cellular meshwork IDs on your iPhone or iPad active at once – two eSIMs and one SIM or three eSIMs ? Or even more ? You might think Apple is trying to frustrate you . But it ’s a ironware limitation that ’s design around what Apple think represents the Brobdingnagian majority of its substance abuser ’ needs .
The curt answer is that Apple has the necessary hardware built into some iPads and iPhones could allow two ( iPad ) or three ( iPhone ) cellular subscription at once , but the architecture of those devices only reserve one ( iPad ) or two ( iPhone ) to be in enjoyment at any yield meter . Newer U.S. models of iPhones have only the circuitry required to manage two active cellular subscriptions , not three , realise it an entirely arguable percentage point .
Let ’s labor into the details .
SIMpathy for the traveler
During the burst of smartphones , the Mini SIM formatting was prevailing and valuate about 1 by 0.6 in ( 25 by 15 mm ) . Most of that was a plastic environs to protect the circuitry . However , the form factor shrunk over several years to Nano , about 0.5 by 3.5 inches ( 12.3 by 8.8 mm)—otherwise known as “ the size that when you send away it , it will slip into any crack cocaine and be lose evermore . ”
Due to high-pitched roaming price , SIMs were a convenient way for travelers to cut costs by installing a SIM for a local religious service plan in the country or region they arrived in . A common task for many people upon entering a country other than their own was to ascertain an drome kiosk or convenience store , buy a SIM with a cheap program , find a paperclip or SIM removal creature , and carefully swop out the SIM . You could eventually pre - purchase these SIMs , but I hark back a very ho-hum time of swapping four Nano SIMs for my family on landing in London after 14 hours of flee .
The limits on total SIMs
With a SIM / eSIM iPhone or iPad , you’re able to activate the eSIM as the only cellular plan on your equipment . In Apple ’s funny phrasing , you’re able to install “ eight or more ” eSIMs – why not one or more if the company does n’t assign the top bound ?
An iPad can only have a single SIM or eSIM dynamic , but you could use the Dual SIM feature article starting with those iPhone models above with iOS 12.1 or later . To use 5 gramme this way , you postulate an iPhone 12 series phone or afterward with Io 14.5 or by and by installed .
The two-fold SIM lets you spark off a SIM and eSIM or , starting with the iPhone 13 serial publication , either that or two eSIMs at once . Apple eliminated the SIM module from iPhones sell in the United States , start with the iPhone 14 models .
Because an eSIM is a physical piece of computer hardware , the limitation on how many SIM / eSIMs you could use is strong-arm , too , not an arbitrary software limitation :
For that last choice , I assume Apple did n’t think the extra cost of support a SIM plus two eSIMs made any sense for its user base , particularly since the company was already moving to reduce the price of goodness with its geological fault to eSIM - only iPhones in the United States .
Eventually , when eSIMs are support by the vast majority of carrier ( a stage we ’re nearing ) Apple will certainly ditch the SIM slot on all iPhones and iPads worldwide just as it got rid of the earpiece cud on iPhones years ago .
