Internet through 3G stick (Moviestar, Mass-Movil) is possible if the location is no that far from the main antennas like sant carlos, cala boix, etc..
A cheap 3G - Stick you can get from the partysan guys. Their office is behind "Feta" close to the round about to pacha. just try to contact them through facebook or so. compared to
moviestar they have a much better offer.
Ibiza town seems to be covered by 3G, until San Jordi.
Otherwise I can recommend "Net-Stumbler" to find the next wifi router easy, asking the neighbors helps in the most cases.
around 20/30 per month whereby they charge both for the modem around 60-80. the speed depends where your are. in remote locations you can be lucky to get more than 150k, in the city its limited to 300-700k. the upload is not that faster than 30k.
if you are around the towns, telefonica offers at them moment 1000k lines. we had to take 3 of them to get something proper because even such "serious" providers throttle you in the main traffic times down to 300k, sometimes.
if it helps, we placed an additional "domain controller" in our office and sync our work over its "DFS" to the internet. this makes working incredible fast for us. however, depends what you're doing.
book your broadband line early enough, the service just s*** here. good luck.
There might be a misunderstanding, I meant with 1000k actually the 10Mb offer from telefonica.
3G traffic is limited(1.5GB), but yes; you can pick up a sim card from movie-star or partysan(mas-movil). Sometimes its even faster than the DSL in some areas.
There is indeed a guy who can install a long-distance wireless connection which runs with 3Mb as its best for 100 bugs per month and the modem is around 800+. I heard its quit good.
You can also rent an external root server with a 10MegaByte/sec connection. The best fit at the moment is 1&1 for 85+ euro per month. After the setup you can connect with remote desktop connection to your terminal. Its pretty easy ! I've been working like this with a simple 300k connection and it was quit OK.
The land-line-dsl setup could last 3-8 weeks if you start from scratch, also depends to the location. Minimum duration for the contract is one year. The upload rate of the mentioned 10Mb connection from telefonica is around 30Kilobyte/sec and the 3G-Stick doesn't come over 15-20KB/sec.
And Satellite s** even more
do you sorted out your accommodation yet ? some landlords here are quit nice and help ..
