Need Advice: Company Expecting Me to Use Personal Phone for Work

I recently landed a Talent Acquisition position at an IT company, but I’m facing a challenge. They’re asking me to use my personal phone and SIM card to contact candidates during the resume screening process. Due to recent telecom rate hikes, I’ve only opted for a calling plan, but now the company insists I get a separate data pack since the office Wi-Fi only works on company laptops.

I spoke with my manager about this and expressed that I plan to use my SIM solely for work purposes, so I requested reimbursement for the recharge. Unfortunately, they informed me that the Talent Acquisition department doesn’t receive any separate phone allowance.

It’s only my first month on the job, and I had to recharge using money from my father, which makes me feel guilty since my stipend is quite low.

As a new recruit, I would appreciate any advice on how to navigate this situation. Thank you!
