I don’t get this data sim only thing
I have a 3 sim in my iPhone with unlimited data.
I can take it out of my phone put it into an adaptor and it works fine in my
mifi.
Am I missing something here.
No. They work on Three. But you can't make phone calls through a
MiFi.
Hence my boring posts about how there are ways to do it with a suitable router, and plug in a telephone to still have the voice calls.
Other networks are available, e.g GiffGaff PAYG. Currently the £20 goodybag includes 40 Gbyte data and unlimited everything else. I think their EU roaming cap is 20 Gbytes. Turn off the goodybag in months when not needed. No commitment, no contract, no credit check.
Top up every three months, minimum £5, and you get free GiffGaff to GiffGaff calls, that's what my partner and I do, use them like walky-talkies in rugged waterproof handsets from Aldi, £20 each. The smartphones live in the safe except when we are back at the van.
Their batteries last weeks, they boot up in seconds, have bluetooth, good FM radio, really sensitive, and I've even managed to configure them as 3g WiFi hotspots and for e-mail, but that is a techy thing to manage, manual configuration of APNs, email settings etc. No instructions, you have to work it out for yourself. Twin SIM too. Second SIM GSM only, as usual.
Smart phones are all very well, but "dumb" ones still have their uses. And the Aldi ruggeds really are rugged, survived drops, capsizes in our racing dinghies, foul weather, other abuse, they have buttons, not fragile glass touch screens. Not attractive to thieves either. They make and receive calls, WiFi hotspot, Bluetooth, basic e-mail, text, very good FM radio, media player, SD slot, all the basics, nothing else.
Usually we put our Three unlimited ones in the primary 3g slot where they work, and the GiffGaff in the second 2g only.
TBH the delicate expensive smartphones mostly live in the safe, we do our stuff with tablets and laptops tethered to the cheap rugged phones, either over Three 3g which is good enough, or activate the goodybag, put the Three SIMs back in the smartphones, the GiffGaff into the 3g slot and run on GiffGaff. That way we could have a total of 49 Gbytes/month, roaming.
Sometimes even tether the smartphones to the Aldi ones
Network is O2 and frankly superior coverage to Three, particularly in remote places.
Not tried the GG SIM in a
MiFi or other data device, but I expect it might work.
