Hi, cant help with mobile shop(differrent area) but I,m on tesco mobile which is 02 and get brilliant partner signal with movistar. Do you have "roaming" set in your settings? Also have you gone to your settings, select mobile networks to see list of signals in that area and choose a partner network which 02 has as a partner. If you choose "select automatic network" it will register your mobile to 02,s partner.
Dont know if this helps, but sometimes going back to basics works. I dont know if 02 lets you use a roaming partner but tesco does which is on 02 signal in Uk and movistar in Spain. I do use a spanish sim too, "Hits mobile", it uses vodafone es. network and is cheaper than the big names and it has an excellent english website with top ups online. I,d recommend them(use in a house alarm and keep one in phone just in case my tesco loses signal. Once you,ve got the sim, top ups online and customer service all in english
Good luck
Pauline.
