Absolutely the best solution to getting a Nexus 7 WIFI hookup is to get the
4620L 4G hotspot.
It is 4G, 3G etc.
It works anywhere globally. It can connect to cdma, gsm, etc. Just make sure you understand foreign carrier charges when you travel.
I get up to 65 meg speed throughput when I'm in a 4G area, yet only 28meg when connected to my home WIFI through FIOS. That's screaming, either way.
This 4620L hotspot is smaller than a pack of cigarettes and can connect up to 10 WIFI clients.
A major reason for buying this, is that you can set a very long and complicated wpa2 security password to protect your ID and online wallets.
Prior to buying this, I
only connected to public WIFI networks when I could also join a free SSH VPN. That seems no longer an alternative, since all the free vpn services I tried only seem to work for about 1 or 2 days. That left me with 3 choices:
1. No security on public WIFI
2. Pay monthly to join a VPN
3. The Verizon 4620L hotspot. (Forget about their 4610L 3G model. It can't hold a candle.)
PS
I have always been an early tech adopter, (Car cell phones in 1983, computer in 1978), but have always resisted getting a smart phone.
We still use the LG 8300 Verizon phones, because they have 2 separate speakers and because your hearing is the
2nd thing that goes when you're in your 70s.
Besides that, smartphone screens are to small for internet surfing. The Nexus 7 is perfect in every respect and even fits into almost every pants pocket.
Oh, before you ask, the
1st thing is ingrown toenails.
