I am very delighted with the results that I have obtained by using the Mytello dial in number. I have not used the app for anything other than topping up my credit and keeping an eye on the available balance. My regular phone service provider allows for international texting and has plans with included international call minutes, 100 or 200 depending on the plan. Unfortunately the list of countries is limited to about 35 or so. I found Mytello almost accidentally, it suited my needs perfectly. I have since found other similar providers but they were in fact more expensive. Thank you Mytello. Thank you very much also to Martin for his excellent customer service and support.
