With reference to https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X230-Laptop-4G-LTE-in-the-UK/m-p/2258754#M681... - trying to find a Lenovo FRU 04W3821 is like trying to find Rocking Horse doodah....
What other options are there for UK based WWAN cards ?
i.e. the next best thing ?
I'd love to have my x230 be 4G capable, however, I'd settle for a decent, and working 3G.
I've got the cables internally - just not the card.
I've found one that is being advertised as ... "60Y3255 60Y3279 04W3767"
Another as "60Y3297"
Another as "04W3786, 60Y3297" - stated as same model.
And finally - a " 04W3767"
I am not 100% sure about GPS or not - I use Linux, not Windows, so don't know if that would work, I guess, if there is a GPS that works (especially under Linux) then that would be a bonus, not a necessity.

Welcome to the Community

with 3g+LTE capabilities? In UK and for x230 - nothing else, only mc7710.
> I'd settle for a decent, and working 3G.
Sierra Wireless mc8355 (Gobi 3000)
I'd not recommend to use Ericsson F5521 as it might be a firmware quality lottery, this modem is very old.

60Y3255 - Ericsson F5521gw
60Y3279 - F5521gw, Vodafone & AT&T SKU
04W3767 - F5521gw, Japan SKU
60Y3297, 04W3786 - the same, H5321. The FRU differs because of its coding format changes
One more Ericsson' modem:
60Y3277 - F5521gw, Vodafone SKU
60Y3257, 04W3785 - the same, Sierra mc8355 (Gobi 3000)
GPS receiver should work via modem' antenna AUX port. WWAN modem sends the data to the system via NMEA serial port if the driver is present. The location application or driver or some tool should be capable to control (turn on/off) the GPS receiver. It's possible to do that via serial port of the modem using AT command but I don't know it for Ericsson modems.

That's a great start.
I take it the MC7710 has to be the Lenovo FRU - otherwise the BIOS won't let it work ?
If not that one - then either...
60Y3297 / 04W3786

yes... if you can't or won't perform some efforts and actions in order to adapt a Sierra generic modem mc7710 or its branded versions for another laptop vendors (Dell, HP, Apple etc). Of course, these actions aren't official. The advantage of non Lenovo' branded modems mc7710 purchasing is their lower price.
The choosing between H5321 and mc8355 depends on:
- your mobility as the 1st modem supports WCDMA/HSPA/EDGE/GPRS networks (Europe and most countries) while mc8355 supports CDMA/EV-DO networks also, mainly in the USA and partially in Asia and some coutries. I.e.mc8355 can work almost worldwide
- H5321 is a bit faster: DL speed 21 Mbps / UL 5.76 Mbps vs 14.4 Mbps / 5.76 Mbps of mc8355
- both modems are stable, reliable enough, can work under Linux (AFAIK). The only relative disadvantage of mc8355 is its firmware management method. This modem has specific fw images for a lot of cellular carriers like Vodafone, Verizon, T-Mobile etc (about 10 in total), as well as the generic fw image for almost any WCDMA/UMTS cellular carrier. Apropriate fw image has to be applied (loaded in modem) depending on the carrier. Not every SIM card can force to do it in the automatically mode, so the driver or connection manager has to do it (or to change it) itself. Fortunately, it's a well done task by Linux users.
- of course, both these modems are cheaper than any mc7710 one in the aftermarket.
Note: as H5321 is a half sized modem, you have to have special adapter in order to fix the modem in x230' wwan slot. Usually the H5321 sellers offer that adapter in the kit:
So, up to your choice. )
