As usual everything went smooth as silk. DoctorSIM team is always ready to help and assist to complete your transaction is a professional and friendly manner. Topping up from abroad to help a family member or a friend in a few minutes is priceless. Thank you again!
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.
iPhone 16 Plus Unlock Service
I ordered an unlock service for my iPhone 16 Plus locked to T-Mobile (USA) and the process was completed in barely two business days. I highly recommend doctorSim for the great service delivery and low prices as compared to other companies.
