Hassle Free & Super Fast Top-ups.
We have been using DoctorSIM for topping up our SIM cards for many years now, and we have consistently had an excellent experience.
The service has always been fast, reliable, and professional, with very reasonable rates and an impressive range of networks available globally. This is a real advantage compared with many other providers in the same business.
On one occasion, we accidentally entered an incorrect SIM/telephone number when making a top-up. As the funds could not be applied, DoctorSIM promptly processed a full refund back to the card we had originally used for the payment. Their response was quick, professional, and hassle-free.
And our most recent experience says it all: we topped up a SIM just a few moments ago, and the funds were credited within approximately three seconds. You simply cannot ask for much better service than that.
All in all, DoctorSIM has consistently delivered a first-class service over the years. We have no hesitation in recommending them 100% and will certainly continue using their services.
i love dr sim
i love this system its fast, user friendly, ive never come across any problems with it and honestly its just so useful and practical, i use it to buy my friend data every so often to help him out, but theres so many other features its so cool!! and i trust that they wont steal my info and sell it or anything too i love dr sim!!!!!!
very nice and smooth experience
very nice and smooth experience. First top to TIM Brasil didnt work because TIM is bad provider. The money stayed in between. So I asked DoctorSIM to change the top up to VIVO (another number of mine) and the money were delivered in 5 minutes to VIVO number, so I could use the data and so on. DoctorSIM works perfectly with top ups.
