Thanks for the reply. Not sure why you said “any iPad that can run iPadOS will also run and be upgradeable to iPadOS 27”. According to this MacRumors post, support for several older iPads were dropped in iPadOS 27.
I’m not quite sure what you mean by “if you rely upon accurate location services for mapping”. If you mean when using Google Maps or Apple Maps, presumably I would do that on my travel iPhone SE?
The SIM issue is discouraging. In November 2023 I went to the Cook Islands in the Pacific. Internet access in the less populated islands is sketchy and when I arrived I went to the Vodafone Store. We tried to enable an eSIM on my (US model) iPhone 14 Pro Max and they couldn’t get it to work. Popped a physical SIM into my (unlocked) iPhone SE 3rd gen. instead, and it worked like a champ. So I feel like I can’t depend on eSIM-only devices to work when traveling to remote places. But the “4 year old devices lose support quickly” argument is compelling.
I really wish Apple hadn’t removed nanoSIM tray support … 😞
iPadOS27
The MacRumours post is inaccurate. Apple, in their WWDC26 Keynote Address, clearly stated that all iPad's that are capable of running iPadOS 26 can also be updated to iPadOS 27 when it is released later this year.
If you are interested, the Keynote can be easily found and viewed from YouTube, AppleTV and other sources. Just search for WWDC26 Keynote using your preferred browser.
Accurate Location Services - WiFi+Cellular vs WiFi Only
To reiterate, only WiFi+Cellular models of iPad have GNSS/GPS capabilities - this being a function of the iPad Cellular chipset. WiFi Only models of iPad have no GPS capabilities with which iPad Location Services can derive location. This fundamental difference may significantly impact your ability to use mapping or other Apps that require accurate/precise location data - in particular if real-time positioning (e.g., a moving map) is required.
WiFi Only iPad models can only “infer” their location from a database lookup of neighbouring WiFi networks for which the geographic location is known, or the geographic location of your public IP address. For static applications in urban locations, where the location of IP public IP addresses and WiFi networks are known, an “inferred” location can be relatively accurate. However, in rural locations, or when using a Cellular/Satellite/VPN connection, location accuracy of an inferred location [if it works at all] may be very inaccurate.
When using Satellite internet systems, such as Starlink, the public IP Address of the internet gateway through which your internet traffic is routed may be in a completely different country/region to your actual location. Where your iPad is using this location to infer its location, you will observe an incorrect derived location.
Cellular Service
While recent models of iPad lack a physical SIM slot, eSIM can offer some significant advantages over those of physical DataSIM.
eSIM equipped models of iPad offer opportunity to provision Cellular service directly from iPad settings - this being particular useful when travelling or if short-term service is required. You are not limited to provisioning a long-term contract with a service provider, but can also set-up a short-term of prepaid data plan directly from iPad settings. The iPad will display a list of available network operators from which you can choose a prepaid plan.
By example, selecting Mobile Data from iPad settings:

Select Find a New Plan...:

Selecting a Cellular Provider from the list will offer a number of available Cellular plans - limited by time period or data volume. Provisioning short-term Cellular Service directly from the iPad is simple - and entirely bypasses the need to find a local retail store from which to purchase a local SIM card suitable for iPad.
Conclusion
Many Users choose a WiFi+Cellular model iPad for its flexibility, even if the need for Cellular connectivity is fleeting. These models also benefit from additional functionality brought about by having access to precise Location Services, using GNSS/GPS, that are entirely independent of having any network connection - whether Cellular or WiFi.
