Lobster answered my queries back last November, some which have been asked here but not yet answered. These are my questions and below their replies, the bold is theirs too
Can I purchase with a non Spanish bank/card?
Yes you can
Must I have the SIM card delivered to a Spanish address?
Yes only to Spanish Addresses
Can I tether with this account and are there limits?
There is a fair usage policy which you can view in the terms and conditions on www.lobster.es
Can the SIM card be used in a myfi router or is it only for use in a phone?
Yes as long as you enter the access point name on the mifi.
Can the whole account be managed from anywhere or must I be in Spain to do so?
We have an application which you can download.
No commitments
You simply pay upfront, every 28 days, for one of our great plans. You’re free to stop and start again any time you like. No lock-ins, no termination fees. We want you to stay because you’re happy with our great service, not because we tie you in.
