Looking for a network configuration advisor (Social Network Service)

The Instagram automation program has web/mobile methods. I have experience with both methods, and the automated method of directly controlling the mobile device (ADB) suited me best. So far, I have automatically configured 10 Android devices, and each device is equipped with a SIM card in a 1:1 ratio. Each device has five Instagram accounts logged in. A total of 50 accounts. A total of 50 accounts interact with each other at set times every day, such as following/liking/commenting. 10 devices process an average of 1500 actions per day. This interaction brings 1.0% of visitors to my website, with 15 unique visitors per day. However, the number of visitors is still low. So I recently purchased 20 more Android devices. What this means is that we will be adding 100 Instagram accounts. But a problem arose. Since I already have 10 sim cards, I couldn't get any more sim cards (due to my country's communication restrictions), and an additional problem was that the sim cards would cost too much. So I set out to find a new solution. GOAL 1. Low cost and high efficiency 2. Connect multiple devices using a small number of SIM cards. 3. The network must bypass Instagram spam detection. The way I already tried I connected my home Wi-Fi to the newly purchased device and attempted to log in to my Instagram account, but as expected, the account was blocked after a certain number of login attempts. 30 accounts blocked :( A method I haven't tried yet MiFi Router (Single SIM) A method of connecting up to 5 devices by installing a single SIM card at a relatively low price 4G/5G SIM card router (Dual SIM ~ Octuple SIM) A method of dividing high-quality cellular data using a router and connecting to new devices. Raspberry Pi SIM card router (proxy server) No detailed information yet. I need your advice to solve this problem.
