I am currently using smspva and dealing with a barrage of pva's within the last few days or so. Not sure if this is in part to instagram kinda freaking out recently or if its a proxy problem or something on my end. Either way I was hoping to get a few opinions in from people who are on both sides of this as pva service is starting to really add up for me as I scale up accounts. I am wondering if it would be better to get sim cards due to the volume of pva I am receiving recently as with those I would not have to pay per text. I guess anyone else who is running 100+ child accounts would be the best to hear from as things are getting pricey even though the results have been excellent thus far!
